Can lemon juice damage permed hair?

Lemon juice is acidic, and when applied to hair, it can cause the hair shaft to become dry, brittle, and more susceptible to breakage. This is because the acids in lemon juice weaken the protein bonds in the hair, making it more prone to damage. Additionally, lemon juice can cause the hair to become discoloured and frizzy.

Therefore, it is not recommended to use lemon juice on permed hair, as it can cause significant damage to the hair. If you do wish to use lemon juice on permed hair, it is important to dilute it with water and use it sparingly.
