Bleach can damage hair by breaking 15% to 20% of its protein bonds. This harms keratin, the protein responsible for hair strength. As keratin degrades, hair becomes weak, brittle, and prone to breakage. To reduce damage, use conditioning treatments and follow proper hair care practices after bleaching.
When bleach breaks down pigments, it also affects the hair’s structural integrity. Over-bleached hair can become thin and frizzy, making it harder to style. Chemical burns on the scalp are another potential risk, leading to irritation or even hair loss. Therefore, careful consideration is needed before using bleach on hair.
Repairing bleached hair involves a few options. Deep conditioning treatments can restore moisture. Bond-building products, like those containing keratin, can help strengthen the hair structure. Regular trims can remove split ends, promoting healthier growth.
As you explore repair options, consider the importance of hair care post-bleaching. A consistent routine, combined with the right products, helps restore vitality to damaged hair. Next, we will delve into specific hair care practices and products that can support recovery after bleaching.
