Before and After One Month of Use


Who is PhD Conditioner for?

Perfect hair Day (PhD) is for anyone that wants more perfect hair days. Whether you have multiple hair concerns or consider yourself to have “healthy” hair, PhD is for women that seek a balance of smoothness, volume, conditioning, strength and polish.

How is PhD Conditioner different than No Frizz, Full and Restore?

PhD Conditioner was specifically formulated to give the ideal balance of the 5 benefits women seek for beautiful, healthy hair—smoothness, volume, conditioning, strength and polish. PhD is for women with multiple hair concerns or those that consider themselves to have “normal” hair. Our No Frizz, Full and Restore conditioners are formulated to focus on a specific concern. 

No Frizz Conditioner eliminates frizz by blocking humidity. Full Conditioner maximizes thickness, fullness and volume. Restore Conditioner repairs and protects dry or damaged hair.

What is the fragrance in PhD Conditioner

All of our products have a light, fresh, citrusy fragrance.

When and why is it important for a product to be sulfate-free?

You've probably heard a lot about sulfates and generally think they are bad for hair. You should watch out for sulfates in shampoos as when they are used in lathering, cleansing products they can strip hair of its natural surface oils, making it feel rough, dry and brittle. Sulfates can also strip the scalp of its natural oils, leading to dryness and irritation. Examples of commonly used sulfate ingredients that can be stripping include: Sodium Lauryl Sulfate, Sodium Laureth Sulfate, and Ammonium Lauryl Sulfate.  You should watch out for these in shampoos.

Sulfates do not inflict damage on hair when used in conditioners or treatments.  When used in these products they actually help make hair smoother, softer and visibly healthier.

Sulfates in conditioners and treatments do not damage chemical treatments or color.  Characterizing them as not good for your hair in these types of products is incorrect.
