About this product
Looking for a hair serum for colour-treated hair that adds satin shine without weight? Olaplex N°.9 Bond Protector Hair Serum is an ultra-lightweight styling serum applied to mid-lengths and ends. It helps smooth the look of frizz, cuts down on tangles and static, and supports the shape of the style you set. Reach for it after your usual products when you want a glossy, polished finish.
What this hair serum brings to shine, frizz and static
Built as a styling serum rather than a rich treatment, Olaplex N°.9 works around a few visible, sensory results: satin shine, better style retention, and fewer tangles and static. It also carries a 450ºF/232ºC heat protection flag and a 48-hour pollution protection flag, both stated in the product data. The texture is ultra-lightweight, so it layers over other styling steps without a greasy feel. Listed ingredients are PVP, a flexible polymer that helps maintain hair style and shape, and Cetrimonium Chloride, which conditions, smooths, softens and has an anti-static effect. It is made for colour-treated hair and goes on mid-lengths and ends as a finishing step.
How much hair serum should you use on colour-treated hair?
Begin with a small amount and build up. Since the formulae is ultra-lightweight, a little covers a lot of ground on mid-lengths and ends. Add more only where hair looks dull or where static and tangles show up. Too much at once can weigh the finish down, so layer gradually until you get the satin shine you are after.
How to apply hair serum to mid-lengths and ends
Press and smooth the serum through mid-lengths and ends, steering clear of the roots. Work it over the hair to help reduce tangles and static, then style as usual. Used last, it helps lock in a satin shine and hold the shape of your style.
Hair serum or hair oil — which suits your routine?
If you are weighing a hair serum against a hair oil, this one sits on the shine-and-style-retention side rather than the rich, heavy side. The ultra-lightweight texture spreads easily through mid-lengths and ends and finishes with satin shine rather than an oily coating. It is designed for colour-treated hair and works as a final step after styling.
