Ryan Forsyth –
After using Olaplex No.4 Shampoo for a few weeks, my hair feels much softer and less frizzy. The split ends have improved noticeably, especially at the ends of my strands. I notice a difference in strength when I comb or style my hair.

My hair was quite damaged from heat styling and chemical treatments. This shampoo helped reduce frizz and gave my hair a more natural, smooth look. It doesn’t leave a heavy residue, which I appreciate.

I’ve tried several repair shampoos, but this one stands out. My hair feels stronger and more manageable. It’s especially effective on the ends where split ends were common before.
