Yes, you can mix bleach and shampoo, and it's a technique sometimes used to create a diluted bleach mixture for hair lightening, known as a "bleach wash."
However, it is crucially important to understand the risks and proper execution before attempting this. Mixing bleach with shampoo can alter the chemical reaction and strength of the bleach.
Here's a breakdown:
-
Purpose: Mixing bleach with shampoo dilutes the bleach, making it less aggressive on the hair. This can be used to achieve a subtle lightening effect or to tone brassiness. It's essentially a less damaging alternative to full-strength bleaching.
-
Method: The reference suggests using equal parts of bleach mixture (bleach and developer) and shampoo. The bleach itself needs to be mixed with a developer before adding the shampoo.
-
Risks:
- Unpredictable Results: The addition of shampoo can change the reaction rate of the bleach, leading to uneven lightening or unexpected tones.
- Hair Damage: Even diluted bleach can cause damage, dryness, and breakage, especially if left on for too long or used on already damaged hair.
- Irritation: Bleach, even in a diluted form, can irritate the scalp and skin.
-
Important Considerations:
- Hair Type: This method is generally better suited for lighter hair colors that need a slight lift. Dark hair may not see significant results and could still suffer damage.
- Strand Test: Always perform a strand test on a small, inconspicuous section of hair before applying the mixture to your entire head.
- Developer Volume: Use a low-volume developer (10 or 20 volume) to minimize damage.
- Timing: Keep the mixture on for a short period, typically no more than 10-20 minutes, and monitor your hair closely.
- Conditioning: Deeply condition your hair after rinsing to help restore moisture.
Important Disclaimer: Bleach washes should be approached with extreme caution. It's always recommended to consult with a professional hairstylist for the safest and most effective way to achieve your desired hair color. They can assess your hair's condition and provide tailored advice. Misusing bleach can lead to severe hair damage that can take months or even years to repair.
