heat's best hair growth oils at a glance:

Editor's Choice: Grows-Mary Hair Syrup, £18.50 on Beauty Bay

Best hair growth oil for thinning hair: Dabur Amla Hair Oil, £4.49 on Superdrug

How do hair growth oils work, exactly? According to research done by the National Institute of Health, oil in comparison to other substances has enhanced penetration, and so the hair oil "reaches up to the hair follicle, and increases the circulation of the scalp". This thereby increases hair growth, while reducing greying of hair (double win).

There are many different types of hair growth oils, each suiting a particular need one has. Plenty of hair oils have ingredients such as rosemary, which, according to Medical News Today, helps by killing "fungi and bacteria" on the scalp. "So, when hair loss is due to an infection or unhealthy scalp, rosemary oil might help." Other ingredients found in hair oil, such as mint, help stimulate nerve growth which speeds up the process.

All of these elements and more can be found in our list of the best hair growth oils below, within which products can be bought from Amazon, Boots, Look Fantastic and more. Let's take a gander, shall we?

Hair growth FAQs

We spoke to Tyler Moore, Expert Stylist at Live True London, on the magical subject of ✨hair growth✨. He answered the most pressing questions we had about growing your hair faster and the products that'll aid you the most on that journey. Here are his insightful hair care tips and tricks below.

Do hair growth oils work?

Hair growth oils don’t technically make your hair grow faster, but they do work to improve your overall scalp and hair health which can in turn lead to hair growth. They can provide vital ingredients to your hair and scalp that aid in the prevention of hair loss, making your hair appear to grow more, and the massaging application of most oils to the scalp will increase blood flow and provide benefits for hair growth.

When to apply hair growth oil?

We love to use hair oil before every hair wash - apply evenly across the scalp and use a scalp massager or your fingers to gently work the oil into your skin. Leave for at least 15 minutes, depending on how fine and oil-prone your hair is, then wash out with shampoo. If your hair is thicker and can withstand oil, leave it on overnight.

How often do you use rosemary oil for hair growth?

Rosemary oil, like peppermint oil, has the same great benefits for maintaining scalp health and improving blood flow to the hair follicles, helping to prevent hair loss and greying. Use at least once a week as a treatment, or apply a few hours before every hair wash and allow to sit. If you have thicker or coarser hair, you can leave it overnight or use it as part of your styling routine.

Why does rosemary oil help hair growth?

Rosemary oil can increase blood flow to the scalp and hair follicles, which can prevent hair loss and in turn make your hair appear to grow faster. Without proper blood supply, your hair follicles cannot get the nutrients they need to grow healthy hair, which can make it appear more sparse and thin. Rosemary oil is also anti-inflammatory, which can help irritated scalps and dandruff, which in turn provides more optimal conditions for healthy hair growth.

Does hair growth cause an itchy scalp?

Hair growth does not cause an itchy scalp. Itchy and irritated scalps are usually caused by hair product allergies, congested scalps, dry and flaky skin, dandruff, or more serious medical problems. Consult your doctor if you have an itchy scalp that does not go away.

Does hair growth slow down with age?

Hair growth does slow down with age.

Does hair growth slow down as it gets longer?

Not necessarily - long hair is more prone to breakage which can slow growth. Shorter hair growing is also more noticeable than longer hair growing. Your hair also has a certain lifespan (determined by genetics) before it will fall out - usually about six years - meaning it will unlikely get longer after this point.
