...iron..even if you get it wet? one of my friends had that treatment done a couple of weeks ago in a hair salon...he told me they used an hair product to straighten his hair and they brushed it backwards until it got perfectly straighten...it's a permenant treatment ..and its not the japanese one...it costs around 60$ ...so i was wondering what kind of product (brush too) they used on him and where can i find it.















the problem was that his old hair (which had a treatment) was perfeclty straight...but the new hair that was growing was curly as usual...so thats why i want to know what the product is called so i can do it myself and avoid spending too much money on updates...can someone help me please?
