expert-approved protection

Learn how common hair aggressors damage hair, and how DAMAGE SHIELD Conditioner protects hair between mask days.

all hair types need daily damage protection


The mask and conditioner serve two different purposes. The mask reverses hair damage in 4 minutes, while the conditioner protects hair from daily damage for up to three days. It is recommended to use the mask first, wait 4 minutes, then apply conditioner for additional softening and detangling benefits. The conditioner will keep the hair protected and soft between mask usage days. 

No, the conditioner will not cause buildup. The gel formula is lightweight, meaning a little goes a long way. Use less than you typically would with a traditional conditioner, and build as needed. You will not experience buildup that way.

No, the conditioner will not weigh hair down. As a result of its lightweight gel consistency, it will soften, smooth and detangle without depositing film-forming silicones or waxes that can build up over time.

No, you do not need to reapply the conditioner for continued UV protection. It will continue to provide protection against UV rays for up to three days.

No, the conditioner does not have SPF. The biotech-produced polysaccharide and fortifying ceramide blend minimizes the drying and damaging effects of UV rays on the hair’s cuticle. This prevents hair from becoming rough, brittle, weak, and prone to breakage.
