Do not order from this company. They will take your money then not send the product. We had to notify the BBB, their states general & a full refund was issued by my credit card then taken back from them. Beware!

Didn’t get the chance to try this as it was spilt all over the box none left

Wow - wish I came in contact with this amazing shampoo and products years ago!

This saved my hair and my sanity! For months my hair was dry and would not style properly; I would have to use so much heat to get it to get anything, which made the texture of my hair worse. I just couldn't win. I tried all sorts of fixes, including heat protectors, in shower masks, you name it, I tried it and nothing was working. Enter PhD shampoo and conditioner, one use and it was back to normal and it's only gotten better with each use. If you have dry and/or damaged hair, I cannot recommend this enough.

Been using this for a while. Hair feels healthy and not heavy.

Shampoo is good but the bottle I received was faulty so I’m now left without a working pump. Customer services has gone completely silent and refusing to replace faulty item.

have used Perfect Hair Day shampoo and conditioner for years and was very happy with the results. My hair looked perfect and stayed cleaner longer just as advertised. I recommended it to everyone! Until I purchased a new 24-ounce bottle and did not notice that you had CHANGED THE FORMULA!! I did notice that my hair suddenly felt limp and greasy the day after washing. Then I noticed that the old bottle said “hydrate and perfect,” while the new bottle says “for dull, dry hair. ” I then came to your website to learn that you had changed the formula. This new stuff is awful. Why would you mess with perfection? Now I am looking elsewhere for new hair care products.

Wouldn't buy again. No benefits so far, too expensive for little return

Lightweight - a small amount goes a long way! Perfect for my fine / thick hair.

After using this and the conditioner a few times, I developed a terrible rash on my scalp. Sadly, I won’t be repurchasing.

Love the fact I only need a really small amount of shampoo. Smells fantastic and my hair feels great. Well worth spending a little extra on.

Absolutely love this shampoo!! Great deal getting the refill bag.

I have used this since it first came on the market, it’s one of the best shampoos ever !

Unfortunately, this is too drying on my hair. Have been using with the Perfect Day conditioner and my hair does not like it at all: will be stopping using it.

Early days, brought the travel size to test. Hair feels soft and silky. Feels nice and clean.

Game-changer; transformed my over-processed, brittle blonde hair into the locks of my dreams; swishy, silky and super healthy. Thank you Living Proof- never going back.
