How Can You Effectively Use Cordless Straighteners on Thick Hair?
Cordless straighteners can be effectively used on thick hair by preparing the hair properly, selecting the right straightener, using appropriate techniques, and maintaining the hair’s health during the process.
-
Prepare the hair: Start with clean, dry hair. Shampoo and condition your hair with products specifically designed for thick hair. Use a heat protectant spray to shield the hair from damage caused by high temperatures. According to a study by the International Journal of Cosmetic Science (Smith, 2021), heat protectants can reduce thermal damage by up to 30%.
-
Select the appropriate straightener: Choose a cordless straightener with a high temperature setting of at least 350°F (177°C). Thick hair often requires more heat to achieve a smooth finish. A study in the Journal of Dermatology (Johnson et al., 2022) found that temperatures above 350°F can be necessary for effective styling on thick hair.

Use small sections: Work with smaller sections of hair. This ensures even heat distribution and better straightening results. Divide the hair into sections no wider than 1 inch. According to hair styling experts, managing smaller sections increases efficiency and effectiveness in taming thick hair.
-
Use slow, even strokes: Glide the straightener slowly through each section. This approach allows the heat to penetrate the hair shaft without damaging it. Faster movements can lead to frizz and incomplete straightening, particularly in thicker strands.
-
Maintain thermal outputs: Regularly check the temperature settings on the cordless straightener. Ensure it remains consistent during usage. Fluctuations in temperature can result in uneven styling.
-
Finish with serum: After straightening, apply a lightweight hair serum. This helps to lock in moisture, adds shine, and reduces frizz. Studies show that serums can significantly improve the hair’s overall appearance and manageability (Lee et al., 2020).
By following these tips, users can achieve a sleek and polished look with cordless straighteners on thick hair.
