I focus this mainly on my ends and it really helps with split ends and dryness. The texture is nice and not too thick. Takes a while to see major results but definitely helps with overall hair health.
Quick answers to the questions people ask most.
Kerastase hair oils are formulated for various hair types including dry, damaged, frizzy, and color-treated hair. Different oil formulations target specific concerns like shine enhancement, heat protection, or intensive nourishment. Consult the product description or a hair professional to find the best oil for your specific hair type.
Apply a small amount of oil to damp or dry hair, focusing on mid-lengths and ends while avoiding the scalp. For fine hair, use 1-2 drops; for thick or coarse hair, use 2-4 drops. The oil can be used before styling for heat protection or as a finishing touch for added shine.
Yes, Kerastase hair oils can be applied to both wet and dry hair. When applied to damp hair, the oil helps seal in moisture and provides heat protection during styling. On dry hair, it adds shine and helps tame frizz throughout the day.
Most Kerastase hair oils can be used daily as part of your styling routine. Start with 2-3 times per week and adjust based on your hair's needs and response. Overuse may weigh down fine hair, so monitor how your hair feels and looks.
Authentic Kerastase products are available at authorized salons, beauty supply stores, and official retailers like Sephora or Ulta. You can also purchase directly from the Kerastase website or authorized online retailers. Always verify the seller is authorized to ensure product authenticity.
Unopened Kerastase hair oil typically lasts 2-3 years from the manufacturing date. Once opened, it's best to use within 12-18 months for optimal effectiveness. Store in a cool, dry place away from direct sunlight to maintain product quality.
Yes, most Kerastase hair oils are specifically formulated to be safe for color-treated hair. Many formulations actually help protect color and add shine to chemically processed hair. Always check the specific product label to confirm it's suitable for your hair treatment type.

This hair oil has completely transformed my dry, damaged hair. After using it for about a month, my hair feels incredibly soft and looks so much shinier. The scent is luxurious and it doesn't weigh my hair down at all. A little goes a long way, so the bottle lasts quite a while. Definitely worth the investment!
This oil absorbs quickly and doesn't leave any residue. My hair feels so much more manageable after using it regularly for a few weeks. The only downside is the small bottle size for the price, but the quality is definitely there.
Does exactly what it claims - makes hair smoother, shinier, and more manageable. The texture is lightweight and it spreads easily through hair. My main issue is the cost, especially considering how quickly I go through the bottle with regular use.
I focus this mainly on my ends and it really helps with split ends and dryness. The texture is nice and not too thick. Takes a while to see major results but definitely helps with overall hair health.
While this oil smells amazing and seems high quality, it's just too heavy for my fine hair type. Even using just a tiny amount makes my hair look greasy and weighed down. Might work better for thicker hair textures.
Works well for adding shine and smoothness. The price point is quite high though.
After years of coloring and heat styling, my hair was in rough shape. This oil has genuinely helped repair some of the damage and brought back so much softness and shine. I use it as an overnight treatment once a week and as a finishing oil after styling. Can't recommend it enough!
The oil itself works really well for adding moisture and shine to my hair. My only complaint is that the fragrance is quite strong and lingers for hours. Some people might love this, but I prefer more subtle scents in my hair products.
I use this before blow drying and flat ironing, and it provides excellent heat protection while leaving my hair silky smooth. The consistency is perfect - not too thick or thin.
It's a good hair oil that does what it promises - adds shine and reduces frizz. However, I'm not sure it's significantly better than other high-end hair oils I've tried. The scent is pleasant and it doesn't make my hair greasy, but I expected more dramatic results given the price and reputation.
This oil gives me the same smooth, glossy finish I get when I leave the salon. It's become an essential part of my hair routine. Works great on both wet and dry hair, and a little really does go a long way.
I have thick, curly hair that tends to get very frizzy, especially in humid weather. This Kerastase oil has been a game changer! It tames my frizz without making my hair greasy and gives it such a healthy-looking finish. I apply it to damp hair before styling and again lightly on dry hair for extra shine.

Hair oils are typically heavier and provide more intensive nourishment and shine, while serums are lighter and often target specific concerns like frizz or heat protection. Oils are better for very dry or damaged hair, while serums work well for fine hair or when you want lighter conditioning benefits.
