Absolutely thrilled with my keratin treatment. I’ve had it a few times in London at various salons and was never 100% satisfied. I found Hair Go thanks to the reviews everyone else had left, and it didn’t disappoint. It took about 2 hours and the best part was, I only had to leave it in my hair for 24 hours - and it didn’t feel or look greasy like other treatments. After the first wash, my hair was straight and frizz free. Would 100% recommend it and will be coming back
