You bleached your hair, and now it is dry, damaged, and lifeless. Are you wondering how you can fix your locks? What you need to do is simply hydrate hair after bleaching it. Bleaching agents are harsh and damage your hair from within. These agents penetrate your hair cuticles and weaken them. As a result, your hair loses its color, strength, shine, and elasticity. But worry not – discover here how to repair, protect, and hydrate bleached hair.

What Does Bleach Do To The Hair?

Bleaching agents can damage the hair in the following ways:

  • They make the hair dry and lifeless and cause protein and cysteine loss in hair fibers (1), (2).
  • They reduce the hair’s brightness, softness, and manageability (3).
  • The chemicals like ammonium hydroxide and hydrogen peroxide in bleaching products open up the hair fibers, causing inter-fiber friction (4).
  • Bleaching also damages the hair cell membrane complex and endocuticle (inner layer of the cuticle) (4).
  • Bleaching weakens the bonds in the hair, affecting its structural integrity (5). This makes your hair prone to further damage during combing and similar grooming processes. It also increases hair porosity.

If you have recently bleached your hair, there is no need to panic. There are ways you can repair the damage. Scroll down to know more.

Tips To Hydrate And Repair Hair After Bleaching

  1. Hydrate Hair: Right after bleaching, the hair feels dry and flat. Hydrating the hair with natural oils replenishes and repairs it and prevents internal swelling and breakage. Here are a few oils that you can apply post-bleaching:

A study showed that coconut oil could reduce protein loss in bleached hair. Using coconut oil as a pre-wash regimen before bleaching can reduce inter-fiber swelling (7). Moreover, coconut oil acts as a protein shield, reduces hair loss, and promotes hair growth (8).
