Can You Safely Bleach Dyed Hair?
No, you cannot safely bleach dyed hair without potential risks. Bleaching can damage hair that has already been colored.
Bleaching works by stripping color from the hair through a chemical process. When hair is previously dyed, it may contain various pigments that react unpredictably with bleach. This can lead to uneven results, breakage, or excessive dryness. Additionally, the hair cuticle, which protects the inner structure, can become weakened by the dual processing. It is advisable to consult a professional stylist who can assess hair health and recommend safe procedures.
What Steps Should I Follow to Bleach Dyed Hair Safely?
To bleach dyed hair safely, follow these essential steps: assess your hair’s health, choose the right bleaching product, conduct a strand test, prepare your hair, apply the bleach properly, monitor the process, and care for your hair afterward.
- Assess Hair Health
- Choose the Right Bleach
