How Do You Assess the Condition of Your Hair Before Bleaching?

To assess the condition of your hair before bleaching, evaluate its strength, moisture level, and overall health through various simple tests and observations.

Strength: Check for signs of damage and elasticity. Healthy hair has a good amount of elasticity, which means it can stretch and return to its original shape. You can perform a stretch test. Take a strand of hair and gently pull it. If it stretches significantly before breaking, it is likely in good condition. If it breaks easily, it may be weak and not suitable for bleaching.
Moisture Level: Determine if your hair is adequately hydrated. Dry hair often feels brittle and rough. A moisture test can be done by taking a small strand of hair and placing it in water. If it sinks quickly, it indicates high porosity and may be very dry, making it prone to damage from bleaching. Hair that floats is likely in better condition and more adequately hydrated.
Overall Health: Consider the color and texture of your hair. Healthy hair should have a natural shine and smooth texture. If your hair appears dull, frizzy, or has split ends, these could be indicators of damage. A study published in the International Journal of Trichology noted that hair health impacts bleaching results, with damaged hair absorbing more chemicals and experiencing more damage during the process (Johns & Lee, 2020).
Previous Treatments: Take note of any prior chemical treatments such as perms or relaxers. These treatments can affect your hair’s integrity. If your hair has undergone multiple processes, it may not withstand bleaching, leading to excessive damage.

By conducting these assessments, you can make an informed decision about whether your hair is ready for bleaching.
