  • PK4

    This product is definitely worth trying. I am on my third pot of supplements and can honestly say my hair has improved. As others have said in reviews, I can see more baby hairs appearing and it looks healthier. You do have to give it a few months but worth it. Posted on

  • PK4 for thinning hair

    This is my third month of using PK4. My hair was thinning due to menopause and lacking in lustre and condition. I can happily say that this product has saved my hair! Not only am I not shedding hair as before my hair is thick, shiny and easy to manage. I did notice a different after using the product for the first month but after that it just go better. I can HIGHLY recommend. Posted on

  • 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
