Each 18-ml phial of Wella's Perm Pre-Treatment provides the ideal amount of care for your client's hair before a chemical treatment.

Used before a perming or straightening service, it helps the hair develop even waves from roots to ends and balances its porosity to give beautifully smooth hair fibres.

Of course, it's optimised to work with Wella perms and straightening fluid, but it will also work with all other brands.

Comes in a box of 12 x 18-ml phials.

"Service" is an exclusive, salon-only brand.
