Q & As

Philip Kingsley PK4 Hair Protein Capsules, 800g 4 5 4 4
Can probably live without. I have been using this product for about 3 months and have not really noticed a difference in the length of my hair or the thickness, the only thing I have noticed is that I am not losing as many hairs as I use to. It's quite pricey to have to buy every month. It does state that you have to use it for approx 4 months to notice a difference so I may carry on another month or so to see if I can find a difference. 02 April 2014
Softer hair Great for making hair considerably softer. I also noticed less hair shedding from the roots 26 March 2014
Does what it says! I've only been using these tablets for a month and a half but I've already noticed a difference! Even my hairdresser commented on how healthy my hair was which has never happened before! It's definitely got longer and just feels a lot shinier and healthier. Just bought my second box so I will continue using them! 15 March 2014
Great stuff! Heard rave reviews about these and I have noticed my hair to be thicker and shinier! It's also growing faster as are my nails! Very pleased as I wasn't born with the thickest head of hair! :) 26 March 2012
