Olaplex Nº. 9 Bond Protector: Nourishing Hair Serum & Heat Protectant | Softens, Nourishes & Reduces Tangle & Static | For Coily, Curly, Straight, and Wavy, 90 mL / 3.0 Fl. Oz.

Its what the professional hairdressers use & recommend, for a reason....its great for my hair, protects from hot heat hairdryer & straighteners. I feel I'm really protecting my hair & keeping it nourished at the same time.

I wish I'd been using it earlier :D My hair used to end up straw-y when blowdrying it raw. Now it ends up smooth and healthy if I put some of this on it before drying. Definitely worth a try. It's a serum not a spray, one squirt rubbed between your hands then rubbed into my hair works best.

Great serum, perfect for my daughters curly hair

I have curlyish hair that can drop or frizz at any time it is dry and unmanageable. I used Olaplex no. 9 and it changed my hair it felt soft and the curls were defined and the style stayed for days (usually i have to put my hair up after one day) will definitely buy again

I am satisfied.

Olaplex products are fantastic. As long as Amazon keep there prices competitive I will continue to order from them. The serum is wonderful on both curly or straight hair. Protects from heat damage.

I love this product, and use it every time I wash and style my hair. It really protects, and gives it a lovely shine, even on blonde hair!
