Often used to season a variety of dishes, one particular herb has been making waves on TikTok lately, and not for food-related reasons! Instead, it’s gaining attention for something even better – promoting hair growth.

Curious about the herb we’re talking about? It’s rosemary! It’s claimed that rosemary oil can accelerate hair growth and help with itchiness and dandruff, and is even doctor-approved.

Growing long, luscious hair with a simple supermarket herb might sound silly for some, but many are swearing by its effectiveness, with video evidence to support their claims.

So, let’s dive into what makes rosemary oil so special and how it benefits hair growth, shall we?

Does rosemary oil actually work?

Some may think the effects of rosemary oil sound too good to be true, especially when many claim it helps with conditions like alopecia and postpartum hair loss. Well, here’s the scoop – there’s actual science to back it up. Back in 2015, a study found that rosemary oil could boost the hair count of people with alopecia after six months of use.

According to a hair surgeon from Harley Street Hair Clinic, Dr Zayn Majeed said studies have shown it to be effective at healing nerve endings and encouraging hair growth.

Rosemary oil can help improve blood flow to your hair follicles, ensuring they get the nutrients they need. If these little follicles don’t get enough blood, it can lead to hair loss over time.

Plus, the oil’s anti-inflammatory properties help soothe scalp irritation, dandruff, and itching, creating a better environment for healthy hair growth.

So, not only does it help with hair growth, but it also helps keep it healthy.

As fantastic as rosemary oil is for promoting hair growth, it’s not a magic potion for stopping hair loss altogether. Dr Majeed points out that there is no clinical cure for hair loss, although there are treatments and options like hair transplants that can help slow it down.

TikToker @itzamelika provided straightforward instructions for the dos and don’ts of hair oiling, specifically with rosemary hair oil. Her user-friendly tips make it simple for anyone to follow and achieve better hair care.

There are numerous ways to use rosemary oil for hair growth, but one of the simplest methods involves dilution.

If you’re wondering how to dilute it, don’t worry, we’ve got you covered too.

You can dilute rosemary oil with a carrier oil, also known as a base oil or vegetable oil. To do this, mix a few drops of rosemary oil with a carrier oil, such as coconut, almond, or jojoba oil.

Once you’ve thoroughly mixed them, apply the diluted rosemary oil directly to the roots of your hair, focusing on any bald patches, and give it a good massage (much like how you would massage butter onto chicken).

Furthermore, incorporating massage into this process can help increase oxygen supply to the hair follicles and improve blood circulation.

You can also use a scalp massager to give your scalp a thorough massage, which can be more convenient and less messy than using your hands, especially if you want to avoid getting excess oil on them.

Before you rush to buy rosemary oil for hair growth, it’s crucial to know what to look for.

When purchasing rosemary oil, make sure to check the product’s ingredient list and opt for those where you see “Rosmarinus Officinalis leaf oil,” which is the botanical name for rosemary, listed near the top.

If it’s further down the list, it means there’s less of this beneficial ingredient in the product.
