* The type of highlights:
* Traditional foil highlights: These often use stronger chemicals to lift the hair color and can be more damaging, especially with frequent application.
* Balayage/ombre: This technique typically involves less frequent applications and can be gentler as the bleach is applied in a more diffused way.
* Lowlights: Since lowlights deposit color rather than lift it, they are generally less damaging than highlights.
* The strength of the chemicals used: The strength of the developer and bleach used will influence the level of damage. Higher volumes lift color faster but are more damaging.
* The frequency of highlighting: The more often you highlight your hair, the more damage it can sustain.
* Your hair type: Fine, thin, or already damaged hair is more susceptible to damage from highlights. Coarse or healthy hair can often withstand the process better.
* The skill of the stylist: An experienced stylist will know how to apply highlights safely and minimize damage by using the appropriate products and techniques.
* Aftercare: Proper aftercare is crucial for maintaining the health of highlighted hair. This includes using moisturizing shampoos and conditioners, deep conditioning treatments, and heat protectants.
In general, highlights *can* be harmful to your hair because the process of lifting color involves opening the hair cuticle, which can lead to dryness, breakage, and split ends. However, with proper techniques, products, and aftercare, the damage can be minimized.
