ATP at the Harley Street Clinic, London

Hello

I am wondering if anyone has any information or experience with ATP at the Harley Street Hair Clinic?

I am also interested in the long term of ATP, is there any fading or discolouration? I have read that they can occasionally go green/blue?

I use Toppik daily and am keen to stop using it, i don’t like the mess, the long term cost and am not sure about inhaling the fibres in the long term!

The only real review I can find is Spex, and i would like to hear from a few people if possible!

Thank you
