Olaplex No.4p Blonde Enhancer Toning Shampoo 8.5 oz

I've been using Olaplex No. 4P Blonde Enhancer shampoo for a few weeks now on my bleached/lightened hair, and in many ways it's become a go-to for keeping my blonde from getting brassy. The purple toning helps neutralize unwanted warmth after a few washes, and I definitely noticed my hair looked brighter, cleaner, and fresher compared to regular shampoos. It lathers nicely and feels gentle — which is a big plus if you're like me and try to avoid overly harsh sulfates. After rinsing, my hair feels soft and manageable; it doesn't feel stripped or overly dry (something I've experienced with other toning shampoos). My only mild critique: if I leave it on too long, or use it more than twice a week, the tone can edge slightly grey-ish or cool. So I stick to once every 1–2 washes to maintain a soft, natural blonde rather than an icy tone. I'd recommend it for anyone with bleached or highlighted hair who wants to keep brassy tones away without over-drying their hair.
