  • Lots of new baby hairs!

    I wanted to wait a while before reviewing this product so that I could see the full benefits. I started using these tablets because my hair was thinning lots and you could see my hairline (whereas 3 years ago I had super thick hair and lots of it!). I chose this product because I'm a vegetarian and thought it was most likely my diet that was the cause.

    I have been using this product for three months now and I can now happily say that I have lots and lots of new baby hairs growing along my hairline. I'm sure that there are baby hairs all over my head but the hairline is more obvious. In addition to this I have also improved my diet and added lots more protein and iron to it so I can't give full credit to PK4. However, it does say PK4 works alongside a healthy diet, and isn't a replacement for one.

    All in all, I am a very happy customer but this product is a bit expensive so will try and stock up when there is an offer on. Posted on

  • Excellent product

    I used it the first time two years ago under recommendation of the London clinic. I had amazing results: the hair was lucid, shiny and thick. I ordered it again! Posted on

    8 years ago, my hair(due to luck of iron and candida) was absolutely miserable..I tried so many products, hair saloons and finally send my blood work to Philip Kingsley institute and become a patient..For many years I was on supplement 1 and supplement 2 which absolutely with shampoo and conditioner improved my hair 100%, so it finally grow up to mid of my back without breakage. Last 3 years I am on PK4 supplements and my hair couldn't be healthier and more beautiful. This is just another awesome product that keep hair in a excellent shape!!! Thank you for maintaining my hair beautiful at age of 47!!! Posted on

  • Finally a product that works.

    First let me say that I don't ever write reviews just because I have heard in the past that many companies have employees write positive reviews or offer incentives to consumers to write positive reviews so I find it difficult to always rely on them. I do not work for PK and I am a totally honest consumer who would definitely report if these supplements did not work. I have tried numerous hair supplements without any results. I am one of those people who expect to see instant results because I hate waiting. I tried these pills and after the first couple weeks without results I was ready to call it quits. I decided to finish the bottle and by the end of the month I could tell that my hair had finally started growing! I decided to order another bottle and I have to say I now see results! My hair has definitely started to grow and look much healthier. I just finished ordering my 3rd bottle and plan on ordering more when needed. I will say the price is a little expensive for a monthly payment, but seeing how the pills DO work I don't mind paying. I would definitely recommend these hair supplements to anyone trying to grow their hair out. Just remember results may not be instantaneous. Anything worth something is worth waiting for and will take time. :) Posted on

  • the only way is long !!

    With only 2 weeks of using these capsules hair loss has slowed down drastically when washing. My hair feels less brittle as well. I am excited to see the difference over the next month so watch this space :) Posted on
