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 “normal” 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.

Love it.

I use this in conjunction with the PhD shampoo, 5-in-1, and Night Cap, along with the Full Thickening Cream. My hair has never looked or felt healthier, or taken less time to style. I have fine, wavy hair (and lots of it), and this helps it to stay hydrated and frizz-free without weighing it down. Definitely a keeper.

Wonderful products

Love these products Shampoo and Conditioner Perfect Hair Day (PhD)..gave a 4 stars..just because it is hard to get the conditioner out of the container as the product is too thick for the tiny hole it has. Other than that, the products are fantastic...makes your hair look shiny and healthy.

PHD is the best

I am loving this whole line of products. They make my 44 year old hair feel like newborn hair. I cannot express how much I love these products. They make my hair feel so soft and silky and wonderful with the first use. Try them all. I know I am. I am also bragging on them anytime I purchase them at the local retailer. Everyone in line around me knows how wonderful PHD and Living Proof is.
