But, do hair growth oils actually trigger hair growth and reduce hair loss? And, what are the best hair oil options on the market you can invest in to really accelerate your hair growth journey? Keep reading to find out more.

Do Hair Growth Oils Really Work?
Hair growth oils are highly effective in supporting and boosting your natural hair growth, but they cannot cause hair growth or reduce hair loss themselves. Here is why.
High quality hair growth oils are recommended in dermatology and trichology because:
- They are good hair conditioners that improve hair elasticity and prevent and minimise hair breakage
- They nourish your hair shaft and scalp to support and increase hair production, strengthen the roots, and reduce hair dryness and brittleness, and scalp itchiness
- They also form a protective layer over your hair shaft against environmental stressors
According to the German Institute for Quality and Efficiency in Health Care (IQWiG), a single healthy hair on your head grows at a rate of about 1 cm per month.
This amounts to about 12 cm of new hair length growth per year, whether you apply any hair growth oil or not on your strands.
Some people may have faster hair growth and length than others. How fast your hair grows very much depends on a variety of factors including:
- specific hair type
- health conditions
- overall health
- genetics and family history
People with Afro hair for example are known to struggle with hair length retention, because Afro hair is particularly fragile and very prone to injury and breakage.
Hence, the misconception about the fact that Black people’s hair doesn’t grow. The problem is not about the hair growth rate per se, it’s about consistently retaining healthy hair growth once it actually occurs every month.
This is why the American Academy of Dermatology recommends the use of a hot oil treatment bimonthly in the treatment of Afro hair to add moisture and elasticity to the hair.
Furthermore, it is worth mentioning that, contrary to popular beliefs, regular trims help your hair grow longer and healthier, because you are letting go of damaged hair ends.
A well balanced diet rich in proteins is also helpful in supporting your natural hair growth.
As for hair loss, minoxidil is currently considered to be the most effective FDA-approved and UK licensed over-the-counter hair loss treatment for women and the second most effective hair loss treatment for men, after finasteride. It comes as a foam, liquid, or lotion, normally in a strength of 2% or 5%.
When experiencing hair loss, it is best to visit a clinical trichologist and a dermatologist to find out the cause of your hair loss and receive adequate support.
Which Oils Increase Hair Growth? Key Ingredients to Look For
Focus on hair growth oils and serums with lightweight formulas that are fast absorbing and easy to wash off during your normal weekly hair care routine.
Look for hair growth oils that are formulated to improve cellular generation like hero ingredient rosemary oil, prevent breakage, calm scalp inflammation, and maintain its healthy microbiome.
In relation to this, a 2015 study revealed that rosemary essential oil was as effective as minoxidil in supporting hair growth after 6 months in the treatment of androgenetic alopecia, but with less scalp itching as a side effect.
Other essential oils known to effectively support and increase hair growth include:
- Lavender oil and clary sage oil – generate cells growth thanks to linalyl acetate
- Ylang-ylang essential oil – for dry scalps as it can help stimulate sebum production
- Peppermint essential oil – increases circulation to the scalp area where it is applied
- Cedarwood essential oil – balances the scalp oil-producing glands
- Lemongrass essential oil – found to significantly reduce dandruff after a week
- Thyme essential oil and cedarwood oil – found to be helpful in treating alopecia areata
- Tea tree essential oil – can help unclog hair follicles and promote hair growth
Remember that essential oils must be diluted in plant oils and other product formulas before being applied topically. Less is more. Beware of allergic reactions. Always do a patch test before use.
Additionally, hair growth oils containing coconut oil, shea oil, argan oil, olive oil, almond oil, jojoba oil, castor oil, and horsetail plant oil are highly moisturising plant oils known to effectively support the natural hair growth process and strengthen your hair strands.
Due to their high content in natural lipids present in our skin barrier, fatty acids, vitamins A,B,C,D,E, and lauric acid, minerals combined with their antioxidant and anti-inflammatory properties, these plant oils are helpful in creating a favourable environment for hair growth.
Having said that, here are some of the best hair oils and serums for hair growth worth checking out. From fine hair to thick and long hair, and those suffering from hair loss and baldness, there is something on the list for everyone.
