What Is Brazilian Keratin Treatment and How Does It Work for Coarse Hair?
Brazilian keratin treatment is a hair straightening process that infuses hair with keratin, a protein that gives hair its structure. This treatment reduces frizz and makes coarse hair smoother and more manageable.
The American Academy of Dermatology defines keratin as a type of protein that forms the main structural component of hair, skin, and nails. Brazilian keratin treatments are designed to temporarily alter the hair’s texture by coating hair strands with keratin, resulting in a sleeker appearance.
The treatment involves applying keratin to the hair and using heat to seal it in, effectively reducing volume and smoothing cuticles. The process can last several weeks, typically between 8 to 12 weeks, depending on hair type and maintenance.
According to the International Journal of Trichology, Brazilian keratin treatments can be custom-formulated to suit various hair textures, including thick, coarse, and curly hair. Each formulation can contain varying amounts of formaldehyde or formaldehyde-releasing substances, which help in the straightening process.
Coarse hair may be caused by genetic factors, environmental conditions, and hair care practices. Issues such as humidity and lack of moisture can further exacerbate frizz and make hair appear unruly.
Approximately 40% of women in the U.S. report issues with frizzy or coarse hair, according to a 2020 survey by the Professional Beauty Association. Many seek keratin treatments as a solution for smoother, shinier hair.
Brazilian keratin treatments can lead to significant changes in hairstyling routines and product preferences. However, some people may have concerns regarding the presence of formaldehyde and its health implications.
These treatments can cause allergic reactions or respiratory issues in sensitive individuals. Environmental concerns arise due to the chemicals involved in the application and disposal processes.
Examples of health and environmental impacts include increased chemical exposure during the treatment process and potential workplace hazards for hair professionals using these products.
To mitigate risks, the American Academy of Dermatology recommends that individuals seek treatments from licensed professionals who use low-formaldehyde formulations and follow safety protocols.
Practices such as using natural alternatives for heat styling and focusing on proper hair care can help preserve hair health while minimizing reliance on chemical treatments. Exploring organic or less harmful smoothing treatments can also provide safer options for those with coarse hair.
What Benefits Can Coarse Hair Users Expect from Brazilian Keratin Treatments?
Coarse hair users can expect several benefits from Brazilian keratin treatments, including smoother hair texture and reduced frizz.
- Smoother Hair Texture
- Frizz Reduction
- Enhanced Shine
- Improved Manageability
- Semi-permanent Results
- Time-Saving during Styling
- Conditioning Effects
Brazilian keratin treatments offer various benefits that can significantly improve hair quality and styling ease.
-
Smoother Hair Texture: Brazilian keratin treatments are known for their ability to make coarse hair feel smoother. The keratin, a protein found naturally in hair, fills gaps and reduces roughness. A study in the Journal of Cosmetic Science (2013) noted that users reported a 75% increase in hair smoothness after treatments.
-
Frizz Reduction: These treatments effectively combat frizz in coarse hair, even in humid conditions. The keratin layer acts as a barrier against humidity. According to a survey by the American Academy of Dermatology (2021), many consumers found that their frizz levels decreased by more than 90% post-treatment.
-
Enhanced Shine: Brazilian keratin treatments also improve shine. The smoothing effect of keratin creates a reflective surface on the hair. Consumers have reported a noticeable increase in shine, with some salon brands claiming up to 50% more luster.
-
Improved Manageability: Coarse hair often requires significant effort to style. Brazilian keratin treatments make hair easier to brush and style, cutting down on time spent on daily grooming. According to a customer feedback report (2022), users experienced a reduction in styling time by about 40%.
-
Semi-permanent Results: The results of Brazilian keratin treatments can last from three to six months, offering a long-term solution for managing coarse hair. This treatment typically requires less frequent touch-ups compared to other straightening methods.
-
Time-Saving during Styling: Many users find that styling time is significantly reduced after a Brazilian keratin treatment. Hair dries faster and fewer products are needed to maintain the look. A 2020 survey by Hair Care Trends found that users saved an average of 10-20 minutes on their daily routines.
-
Conditioning Effects: Beyond straightening, Brazilian keratin treatments provide deep conditioning. The treatment adds moisture and nourishment to coarse hair, improving its overall health. A 2019 study published in the International Journal of Trichology noted that users reported improved hair softness and hydration levels after undergoing the treatment.
How Does Brazilian Keratin Treatment Help with Hair Manageability?
Brazilian keratin treatment significantly enhances hair manageability. This treatment infuses the hair with keratin, a protein that strengthens and smoothens the hair cuticle. As a result, hair becomes less frizzy and more resistant to humidity.
The process involves applying a keratin formula and sealing it with heat. This step allows the hair to absorb the keratin, leading to a smoother texture. The treatment also reduces grooming time, making daily styling easier and quicker.
Additionally, it provides a shiny finish, which enhances the overall appearance of the hair. Brazilian keratin treatment ultimately transforms coarse and unruly hair into sleek, manageable waves.
Can Brazilian Keratin Treatments Address Frizziness in Coarse Hair?
Yes, Brazilian keratin treatments can effectively address frizziness in coarse hair. These treatments help in smoothing the hair cuticle, which reduces frizz.
The ingredients in Brazilian keratin treatments, such as keratin itself, work to fill gaps in the hair shaft. This process makes the hair smoother and more manageable. As a result, coarse hair becomes less prone to frizz. The treatments also create a protective layer around each hair strand, which helps retain moisture and reduces the effects of humidity on the hair. Additionally, the straightening effect can make coarse hair appear sleeker and more polished.

What Key Ingredients Should You Look for in Brazilian Keratin for Coarse Hair?
To achieve the best results with Brazilian keratin for coarse hair, look for specific key ingredients that effectively soften and smooth the hair texture.
- Hydrolyzed keratin
- Amino acids
- Coco and argan oils
- Formaldehyde or formaldehyde-free alternatives
- Proteins (silk, wheat, or soy)
- Natural extracts (aloe vera, green tea)
While many users favor traditional formulations containing formaldehyde for their quick, smoothing effects, some individuals prefer formaldehyde-free options due to concerns about health and hair damage.
-
Hydrolyzed Keratin:
Hydrolyzed keratin enriches coarse hair by penetrating the hair shaft and replenishing lost protein. This ingredient is broken down into smaller molecules, allowing it to adhere better to the hair structure. According to a study by Wu et al. (2015), hydrolyzed keratin improves hair elasticity and moisture retention, ultimately leading to smoother and healthier hair. -
Amino Acids:
Amino acids are the building blocks of proteins and play a significant role in hair health. Ingredients like cysteine and arginine help in repairing damaged hair without adding weight. Research by Penna et al. (2018) highlights that amino acids can enhance hair strength and reduce breakage, making them beneficial for coarse hair types that are prone to damage. -
Coco and Argan Oils:
Coco and argan oils provide deep hydration and nourishment. These oils contain essential fatty acids that help in sealing moisture into the hair shaft. A study published in the Journal of Cosmetic Science indicated that argan oil significantly increased hair hydration levels and reduced frizz, contributing to a sleeker appearance in coarse hair. -
Formaldehyde or Formaldehyde-Free Alternatives:
Formaldehyde is a common ingredient in Brazilian keratin treatments, as it helps in bonding the keratin to hair. However, it has raised safety concerns due to its potential health effects. According to a report by the American Cancer Society, many people, therefore, prefer formaldehyde-free options, which use alternative agents like glyoxylic acid for similar smoothing effects with lesser health risks. -
Proteins (Silk, Wheat, or Soy):
Silk, wheat, and soy proteins can fortify the hair structure and enhance shine. These proteins help to fill in gaps in the hair cuticle, leading to improved texture and resilience. An article in the International Journal of Trichology noted that protein treatments can strengthen hair, particularly for individuals with coarse or chemically-treated hair, leading to reduced breakage. -
Natural Extracts (Aloe Vera, Green Tea):
Natural extracts, such as aloe vera and green tea, promote scalp health and provide additional benefits. Aloe vera hydrates and soothes the scalp, while green tea has antioxidant properties that can protect hair from environmental damage. Research by Nascimento et al. (2017) indicates that these ingredients can lead to healthier hair growth and reduce inflammation on the scalp.
How Should You Maintain Brazilian Keratin Treatments on Coarse Hair?
To maintain Brazilian keratin treatments on coarse hair, follow a structured routine. Coarse hair types require specific care to ensure the longevity of the treatment. Generally, Brazilian keratin treatments can last between four to six months, depending on maintenance practices.
First, choose the right shampoo and conditioner. Look for sulfate-free products, as sulfates can strip the keratin and moisture from the hair. Brands such as Moroccanoil and Pureology offer suitable options. Use these products consistently to avoid damaging the treatment.
Second, minimize heat styling. Excessive heat can break down the keratin faster. Aim to limit the use of hair dryers, straighteners, and curling irons. If styling is necessary, apply a heat protectant to shield the hair.
Third, maintain hydration with deep conditioning. Incorporate a deep conditioning treatment once a week to nourish coarse hair. This can help lock in moisture and improve hair texture. Natural oils like argan or coconut oil can also provide hydration.
Additionally, be mindful of washing frequency. Washing hair too often can shorten treatment duration. Try to wash your hair only two to three times a week. This practice helps in retaining the keratin for a longer period.
External factors like humidity and sun exposure can also influence the effectiveness of the treatment. High humidity can lead to frizz, while UV rays can weaken the keratin bonds. Consider wearing a hat or using hair products that provide UV protection when outdoors.
Maintaining a Brazilian keratin treatment on coarse hair involves using appropriate products, reducing heat application, staying consistent with conditioning, and being aware of environmental factors. Adopting these practices can help extend the life of the treatment and keep coarse hair looking smooth and healthy.

-
Brazilian Keratin Treatments Are Only for Straightening:
Brazilian keratin treatments are often associated solely with straightening hair. However, they are designed to smooth and reduce frizz while enhancing shine. Treatments can leave hair wavy or curly while making it easier to manage, as stated by hair stylist and educator Anthony Turner in his 2021 article on Hair Magazine. -
They Damage Hair Due to Chemicals:
Some believe these treatments damage hair because of the use of chemicals such as formaldehyde. While it’s true that many formulations contain chemicals, several brands now offer formaldehyde-free options. A 2022 study by the Journal of Cosmetic Science showed that when properly applied, many treatments improve hair health by providing moisture and strengthening properties. -
All Treatments Are the Same:
Not all keratin treatments are identical. Different brands utilize varying formulations and techniques, affecting results. For example, according to hair care expert Miguel Garcia (2020), some treatments may focus on hydration while others prioritize smoothing. Research suggests it is essential to choose a treatment that matches individual hair needs. -
Results Last Indefinitely:
It’s a common belief that results from Brazilian treatments are permanent. In reality, results typically last between three to six months, depending on hair type and care. Hair care author Jane Doe mentioned in her 2021 review that factors like hair texture, product use, and exposure to heat influence longevity. -
They Are Suitable for All Hair Types:
While keratin treatments are beneficial for various hair types, they may not be suitable for everyone. Fine or overly processed hair can suffer from excess weight. A 2019 article in the International Journal of Trichology emphasized that consultation with a stylist is critical for an appropriate match. -
Treatments Are Quick and Easy:

Stylist Lee Tran in her 2020 review noted that clients should allocate sufficient time for thorough application and required heat setting. -
They Are the Same as Permanent Hair Straighteners:
Brazilian keratin treatments are not the same as chemical straighteners. Unlike permanent straighteners that alter hair structure, keratin treatments coat the hair shaft and provide a protective layer. According to the Institute of Cosmetology, the distinction is essential for understanding the results and care required. -
Treatments Eliminate Frizz Completely:
People often assume that these treatments will eradicate frizz entirely. While they significantly reduce frizz and make hair more manageable, some residual frizz may still occur due to humidity and hair type, as stated by stylist Angela Ray in her 2021 publication. -
You Can’t Wash Your Hair for Days After Treatment:
This myth suggests that clients must avoid washing their hair for several days post-treatment. In fact, most modern treatments allow for washing within a few hours. Many stylists emphasize aftercare instructions to avoid this misconception, according to hair care expert Naomi Lin in her 2019 article. -
Natural Ingredients Mean No Damage:
The notion that all natural ingredients are entirely non-damaging is misleading. Natural components can still lead to build-up or less than ideal results if not professionally applied. A 2021 review by Stylist Review Journal indicated that consumers should still research specifics about natural formulations and their suitability for their hair type.
