It’s worth repeating here: Argan oil is not going to fix or repair your ends. However, it will temporarily and superficially help improve the appearance of them. How and why? Thanks to its ability to gently coat the strand, lock in moisture, and improve shine. 

First up, the nutrient profile of lipids help it form a protective barrier around strands. “It’s great for many conditions, especially dry, damaged hair because its trove of fatty acids lock moisture into the hair follicle,” says Bindiya Gandhi, M.D., an American Board Family Medicine physician and mbg Collective member says about argan oil for hair. “I use it on the ends of my hair to protect from heat styling damage.” But unlike heavier oils, this is light and fast-absorbing enough that it won’t weigh hair down—making the ends appear lifeless. 

Additionally, the oil helps strands reflect light—further masking any splits and frays. According to hairstylist Lucia Casazza, using argan oil can help transform the appearance when used on the ends: “I simply apply it as a leave-in treatment before and after a blowout for a clean, polished look with silky, smooth ends.” 

It’s so easy to use as well: Work a small (dime size) amount of the oil into your palms, warming it up. With your hands and fingers, gently apply it mid-shaft to tip on damp hair or prior to using a hot tool. For touch ups, you can apply a pea-size amount to just the ends as needed.
