ar-gan OY-il

Indigenous to Morocco’s Atlas Mountain Region, this fairly-traded, organic Argan Oil is derived from the Argan Tree and is naturally rich in poly-unsaturated fatty acids, including Tocopherols (Vitamin E), and Omega-6 and Omega- 9 fatty acids, which are known for having restorative and protective properties on the skin.

SA'flow'r OY-il

Safflower Oil, extracted from the plant's seeds, consists primarily of linoleic acid triglycerides. It is a carrier oil, also considered hydrating to the skin and used in lotions and conditioners.

SEH-sah'-mee OY-il

Sesame Oil, which is a refined moisturizing oil derived from Sesame Seeds, has the same emollient properties as other nut and vegetable oils and is commonly used as a carrier oil for skin care products. Absorbs easily and softens the skin.

A-prih-kaht KUR-nuhl OY-il

Apricot Kernel Oil is extracted from apricot kernels and has a very high Vitamin E content (aiding fast absorption) and is a trygliceride composed of 75% oleic acid and 20% linoleic acid, and unsaturated fatty acids esterified with glycerin - similar to avocado oil and sesame oil. Found to be highly compatible with the skin. Apricot Kernel Oil moisturizes and softens skin while helping retain clarity and suppleness.

Why did you choose this?
Kiehl's Since 1851 Store
This is the best argan oil one can buy and one bottle lasts me for a while. I had an inch of hair when I started using it. Now my hair is around my shoulders. By the way, I don't mind if I get the oil on my face since the benefits go to the skin as well. Great product.

does it have silicones?
A shopper on Jun 18, 2012
Best Answer: I checked the ingredients but cannot tell if any of the chemical names indicate silicones.

I will say this product remains oily after spraying. I did not try using a hair dryer or any other treatment after applying the oil concentrate. It stays too oily for my tastes, but it does work wonders on very dry hair like mine.

After applying this product , do I have to rinse my hair OR keep the substance on my hair?
Tuzun P on Sep 7, 2012
Best Answer: You're going to keep it in your hair. I tried using it in the morning and put it on before my other styling products and styling my hair. My hair was super soft but the smell was a little too strong for my taste for the day, I now put it on before bed to soften my hair for the next day. I enjoy the product a lot, just wish it was scentless.

Can this be used on dry hair?
Leslie I on Mar 2, 2013
Best Answer: I've only used it on my hair when it's wet. I sprayed it directly on my hair about 3-4 times and I have found it to weigh my hair down too much and looks greasy. Perhaps I'm using too much though. If you try it I would suggest spraying only one spray on your hand and then running it through your hair.

Can this be used by men?
A shopper on Nov 2, 2013
Best Answer: I don't see why not. It's great for dry hair and absorbs well so that it doesn't appear oily. Just don't use too much, a little goes a long way! I usually spray it onto my hand and rub it into just my dry ends to prevent using too much.

Do you leave this in your hair and wash it out, or put it in before/after you style it?
melanie s on May 30, 2012
Best Answer: This is a leave in treatment, I sometimes put it in my hair after I wash it so it will be shiny when I blow dry it, or I have put it on my hair after it dries to give my hair shine and smooth fly aways. You do not wash this out, be careful not to use too much it will make your hair stringy! Hope this helps answer your question!

When spraying it, is it a mist or squirt?
Ely C on Feb 12, 2014
Best Answer: It's a mist, until the end then it kinda squirts....
Beware, you want this on your hair- not misting on your bathroom floor, it gets slippery!!
But I really like this product!

How does this product compare to the Strengthening and Hydrating Hair Oil-in-Cream?
A shopper on Mar 23, 2014
Best Answer: Sorry, not sure but I really disliked this product and gave it to my mother. her hair is much thicker than mine, mine is fine, and she did not like it at all. to be honest i wish we could return it for something we'd actually use.. seems to make any hair greasy looking even if just use a limited amount or spray in hands and rub together prior to applying to your ends. I would never recommend it.

Is this also a heat protectant from hair dryers, flat irons?
A shopper on Sep 20, 2012
Best Answer: I have not tried the Deeply Restorative Smoothing Hair Oil in conjunction with hair dryers or flat irons so can't make a recommendation. I love Kiehl's Superbly Smoothing Argan Shampoo and Conditioner and hoped the Smoothing Hair Oil would keep my hair smooth and frizz-free between shampoos while adding moisture to my very dry hair. While it added some moisture without being heavy, it did not result in smoothing the manageability of my hair.
