The best hair growth oils that actually produce results

It's fitting that the word Mary is featured in Hair Syrup's viral Grows-Mary formula because it's our hail-mary when it comes to hair growth. We've already done a Hair Syrup product review because we're such big fans of the brand. Similar to their Rapunzel Syrup formula, Grows-Mary is a pre-wash treatment enriched with rosemary and thyme, known for its ability to boost hair growth and reduce hair loss. I mean, just look at TikTok - everyone and their mother is raging about its results. Obsessed.

Customer reviews: "This makes my hair feel so silky and has thickened my hair since using it."
"My second bottle. Have used 1-2x per week and enjoying this oil. I have had some growth and my hair feels better."
"I love these hair oils, this one for my scalp, I have noticed a huge improvement in my hair in every way since using this regularly. Very refreshing."

Another TikTok viral favourite, the Nature Spell Rosemary Oil is the rosemary oil you'll want for long locks (read our research above for why rosemary is the bomb). For under £10, you get a hair oil you can use for lengthening, strengthening, fighting dandruff and adding shine. Bonus points - you can use it on your skin too! Yes, using rosemary oil on the skin encourages circulation and lymphatic drainage, therefore expelling toxins from the skin.

Customer review: "I’ve only used this for 2 days since the day I got it, and the results are already showing up!! It takes at least several months to work and improve hair growth, but so far in my 2 days of using this, my hair has gone thick and super soft! It’s not like the TikTok ads you see all the time, but the product is really good. You don’t have to dilute it with other oils as well, you just add it straight in, wait an hour or overnight and wash it out just like that! It’s so easy and you’ll get the best results. Amazing for the price too! I recommend this product so much so if you are looking at reviews or willing to buy this it’s your sign to do so!"

If there's any culture of women who know how to maintain good hair, it's the women of South Asia. Referred to as "Desi girls", these ladies use oils such as the Dabur Amla Hair Oil to create length in their gorgeously shiny hair. Enriched with Alma (Indian gooseberry) as well as a blend of vegetable and mineral oils, this stuff is gold dust.

Customer review: "I am so obsessed with this oil! My hair has been thinning for as long as I can remember. I've been using this oil, massaging it into my thinning parts for about 2 weeks now and I can tell a huge difference already! I never thought it would ever grow! I'm so pleased. It makes my hair so silky, healthy and soft. I will be buying this for the rest of my life!!"

Oh wait, you thought that was the end of the TikTok viral hair growth oils? You were sorely mistaken. Mille's Rosemary Minty Scalp has also gone viral due to its incredible abilities, made with a biotin infusion of more than 20 natural oils/ingredients that promote growth at the root. It's also fantastic at smoothing split ends, which is a big plus for us.

Customer review: "Unfortunately, my hair experienced significant thinning as a result of contracting COVID-19. Desperate for a solution, I came across this product that had gone viral on TikTok, with claims of promoting hair growth. Well, TikTok wasn't exaggerating! I've purchased this product three times already and can see myself continuing to do so due to being so effective.

My routine involves using it 2-3 times a week, applying it the night before I plan to shower in the morning. I distribute several vials onto my scalp and use a scalp massager to massage it in (also bought on Amazon - lol!). With consistent use, I've witnessed a remarkable transformation in my hair. It's become noticeably thicker and fuller, with lots of new baby hairs sprouting, very happy with the results! One bottle typically lasts me around 3-4 months, making it both effective and cost-efficient. This product has truly been a game-changer for me during a challenging time."

If you have fine hair, you don't want a heavy thick formula greasing up your roots. Rapunzel would never. Therefore, opt for the Grow Gorgeous Hair Growth Serum which stimulates and lifts the roots, while promoting growth. This hair serum is filled with natural ingredients such as Biomimetic Peptide, Chinese Scullcap, Organic Pea Sprouts and Red Clover. A luxurious formula, it can be used on towel-dried hair or dry hair, and will not build up grease on the scalp. We love this as much as the Pantene hair serum, so it is high praise from us.

Customer review: "Bought this as I regularly dye my hair so it does get damaged and I wanted to encourage growth…it’s been two weeks of applying morning and night and I’ve noticed a huge difference and it doesn’t leave hair greasy!"

Peptides are protein builders which create stronger strands for you to whip back and forth whilst blasting out Willow Smith. The Ordinary never disappoint with its products, and the Multi-Peptide Serum for Hair Density is no exception. Working similarly to Olaplex products, it is created with an emollient base for effective penetration and utilises a 21.15% concentration of technologies for maximum results. Sciencey - we love it.

Customer review: "I have been using it for a few months and started seeing some baby hair slowly growing. It does take a while to see effect like what other influencers stated. I have used 1 bottle once a month. A bit costly but it seems the only one available in the market at an affordable price point."

You're rushing to work in the morning - you want to add something to your hair that'll help your hair growth journey but don't want to walk into the office looking like a ball of grease. Enter - the Lee Stafford Grow Strong & Long Stimulating Scalp Serum. Ultra lightweight, and infused with a lush scent (acting as a sort of hair perfume), this formula can be used whenever to stimulate your scalp.

Customer review: "I used to see Lee Stafford products very often in Boots drug stores, but never bought one. After using other products, I thought that nothing would help my thin hair which grows very slowly. One day almost accidentally when in a hurry I bought Lee Stafford hair growth serum and decided to try it. I even didn't realise how quickly my hair started to grow after using this serum for a few months. Also, even if the bottle seems small, you need to use just a little bit of this serum, so you can use it for a long time. I want to buy it again and would want to try shampoo also. I think I found something that really works for my hair type. I could say that Lee Stafford products are worth trying because it has some effect on hair."

Looking for something to truly treat yourself on hair wash day? Why not go for a hair mask instead of an oil to grow your hair? The Percy & Reed Give Me Strength Strengthening Hair Mask is scientifically proven to leave hair 66% stronger after just one use. Using its main active ingredient, Sweet White Lupine, the formula encourages cell metabolism and circulation at the scalp level, supporting new hair growth and inhibiting hair fallout.

Customer review: "I really like this product it gives my straight very fine baby hair the feeling and appearance of being thicker and it definitely is much easier to style after I use it. It makes my hair feel and look in a much better condition. I don’t have the time to leave it on for as long as recommended so probably only leave it on for maybe 5-7 minutes before rinsing out but I am still very happy with how my hair looks and feels after using it and it definitely makes styling my hair easier. I would recommend you give it a try. In comparison to other products, I think it is very reasonably priced as you don’t have to use much to get a good result. I Do have to change between products as I usually find my hair gets used to products but I have been using now for about 3 months and I am still happy with the results."

Did you think Weleda just made amazing moisturisers? Think again. The Weleda Rosemary Revitalising Hair Tonic is a post-wash treatment, much like apple-cider vinegar rinses are used, to enliven the scalp, assist growth and strengthen the shaft of each hair. Especially useful for dried-out, bleached hair in need of a drink (literally), this certified natural product will stimulate the scalp as it sits lightly on the roots, getting rid of greasy hair residue.

Customer review: "My hair feels thicker and healthier at the root after using this product from Weleda. It smells lovely and you can use it on damp or dry hair and in-between washes. You only need a small amount too, so this should last a while. Happy with this product for sure."

Our final option is something a little lighter than everything above - hair growth water. Erbology sells a collection of amazing natural waters, including Rose Water, Lavender Water, and of course, Rosemary Water. You can use it as a post-hair-wash-day rinse, and the concentrated rosemary essence will begin to work on your scalp straight away. It's back to basics, in the best way possible. Plus - you can drink it- yes!  Add 1-2 tsp to a glass of sparkling water for a creativity-boosting drink.
