Whether your hair is starting to thin or has always been on the finer side, it’s not uncommon for us to want to find ways to boost the bulk in our hair for thicker-looking strands. Your options are somewhat limited in this area, and many dermatologists recommend a multi-layered approach that involves trying a few different methods to see what works best for you. If you have genetic hair loss, the best solution may be minoxidil (Rogaine) or a more potent supplement, but hair oils can act as a natural topical hair thickening assistant, if you’d rather go that route.
Hair oils are simple to use — apply them to your scalp, massage them in, let them sit for a little bit, and shampoo and condition as you normally would (most are too thick to leave in without making your hair appear greasy). Some should not be applied directly to the scalp without a carrier oil like jojoba, coconut, sweet almond, argan, or grapeseed oil, so make sure you check whether your oil works alone or needs a helper to tame it down.
Here are six of the best hair oils that can lead to thicker, fuller hair and help reverse hair loss over 40.
Marula Oil
Marula oil is rich in proteins, fatty acids, and antioxidants. It can help strengthen hair at the root and follicle, protect against environmental damage, and add shine to dry, frizzy hair. It also has anti-inflammatory benefits that can help relieve a dry scalp and dandruff, both of which can inhibit healthy hair growth. It is described as lightweight — you may even be able to use it as a finishing oil (a little goes a long way).
Does it need a carrier oil? No — feel free to apply marula oil by itself.
Almond Oil
Almonds aren’t just great for your health — they’re amazing for your hair’s health, as well. Almond oil is nourishing, hydrating, and contains anti-inflammatory properties. It can improve blood circulation to encourage new hair growth when massaged onto the scalp and helps reduce breakage.
Does it need a carrier oil? No — in fact, almond oil is considered a carrier oil that is excellent to mix in with other effective oils.
Jojoba Oil
Jojoba oil is one of the most beloved oils for your hair because it offers vitamin E, B-complex vitamins, and zinc — with tons of moisture and hydration, to boot. This oil can balance oil on your scalp, unclog hair follicles, and strengthen strands.
Does it need a carrier oil? No.
Peppermint Oil
Looking for a more invigorating oil that you can (literally) feel working its magic on your scalp? Peppermint oil is the perfect choice, as it boosts blood circulation, stimulates hair follicles, and balances your scalp’s oil production. Some studies even suggest peppermint oil dihydrotestosterone (DHT) levels, which is a hormone linked to hair loss.
Does it need a carrier oil? Yes, always mix peppermint oil with a carrier oil — it’s highly concentrated and can cause skin irritation if not properly blended with a gentler oil.
Tea Tree Oil
Similarly to peppermint oil, tea tree oil is going to let you feel its presence on your scalp, thanks to its invigorating, tingly sensations. This oil stimulates hair follicles and has anti fungal and antimicrobial benefits. It also unclogs hair follicles to help promote growth and can reduce inflammation associated with scalp irritation and hair loss.
Does it need a carrier oil? Yes — always dilute this strong oil with a carrier oil prior to application.
Rosemary Oil
We saved one of the best — if not the best — hair oils for last: rosemary oil. Some studies say rosemary oil can prohibit DHT levels to help prohibit hair shedding. It has anti-inflammatory properties and can balance scalp oil production and strengthen hair to help minimize breakage. This oil is often added to shampoos that are marketed for thinning hair — feel free to add a few drops to your shampoo or use it to create a mask or massage oil.
Does it need a carrier oil? Yes — on its own, rosemary oil can be irritating.
