Supports healthy hair growth
Strengthens to reduce breakage
Even coverage, root to tip
No synthetic growth compounds
A duo of our Hair Oil and Wide Tooh Comb. A concentrated, waterless pre-wash treatment, paired with a comb to work it evenly from root to tip.
The Hair Oil helps strengthen hair, reduce breakage and support healthier-looking growth, using a blend of castor, pumpkin seed, argan and avocado oils rich in essential fatty acids and vitamin E. The comb spreads the oil through the lengths and ends, so every strand gets coated and the scalp gets nourished before shampooing.
Formulated without sulphates, alcohol, parabens or fillers. Just targeted, plant-powered care for scalp and hair.
Includes:
1 × 100ml Hair Oil (glass bottle)
1 × Wide Tooth Comb

Nothing unnecessary
Apply a small amount to clean, dry lashes and brows using the applicator. Sweep from root to tip, focusing on areas that need extra care. Use nightly and allow the formula to dry fully. With regular use, lashes and brows appear stronger, fuller, and more nourished in as little as four weeks.
With consistent nightly use, lashes and brows appear stronger, fuller, and healthier within four to six weeks. Because this formula works with your natural growth cycle, results build gradually rather than forcing rapid growth.
Most lash serums rely on synthetic growth compounds (prostaglandins) to artificially stimulate growth. These can cause irritation, redness, or unwanted side effects.
Our Lash & Brow Oil is a concentrated, waterless blend of plant seed oils that nourishes the follicle and supports natural growth over time. No prostaglandins, hormones or fillers. Just pure, plant powered strength.
Yes. The formula is designed to be gentle enough for nightly use, even around sensitive eyes. It contains no prostaglandins, alcohol, or known irritants. We always recommend a patch test before first use.
Yes. The formula is designed for both lashes and brows. Apply a small amount from root to tip, focusing on sparse or fragile areas.
No. This formula contains no prostaglandins or synthetic growth agents, which are typically responsible for those side effects in some serums.
With nightly use, one bottle typically lasts six months or more. A little goes a long way because the formula is concentrated and waterless.
We do not recommend using it with lash extensions, as oil based formulas can weaken the adhesive and reduce retention.
It is, however, ideal for lash lifts. After a lifting treatment, lashes can feel dry or fragile, and this nourishing oil helps condition and restore them, keeping them soft, healthy, and glossy.
For best results, apply once daily at night to clean, dry lashes and brows. Consistency is key.
Water is often used as a filler in cosmetics. By removing water, this formula remains highly concentrated and potent, meaning every drop delivers active nourishment rather than dilution.
Yes. The Lash & Brow Oil is vegan and cruelty free.
Our formula is made purely from plant oils and vitamin E, with no essential oils, fragrance, or synthetic growth ingredients. We always recommend checking with your doctor or midwife before using any new product while pregnant or breastfeeding.
I’ve always struggled with managing my curly hair and getting my curls to actually define themselves. Since using Isobel Perl, my hair has grown so much longer, feels healthier and looks noticeably thicker, despite being coloured. My curls have also regained their volume and definition, which is something I struggled with for so long. My hair feels so much healthier, and I finally feel like I’m getting my natural curls back! 🤎
The most amazing hair oil ever. I use once a week before my hair wash and the results 😍 this was a Bauld patch 4 weeks before and the growth already. The best brand ever 🫶🫶
I’m 38 pre menopausal and having lost so much hair this oil had been a confidence saver. Thank you so much.
Like most moms, I've gone through severe post partum hairloss and my hair line was looking really sparse. After using the hair oil for only 2 months, I noticed SO much regrowth. My hair line is now full and looks even better than pre-pregnancy. There is only one downside to this product.. I am in a forever baby hair era now 🤣
My hair is also shinier and softer than ever!
Very lightweight and has a lovely smell. My hair definitely grew faster using this! 😍
My hair needed some serious TLC after years of box dyes and a recent colour rewind that stripped my hair of the dye, leaving it worse for wear. I have struggled with a dry scalp and bald patches along my hairline for years now, and have been searching for a solution. I have used all of Perl's current products and they transformed my skin, so my hopes were high with what this oil could do for my hair's health.
After using it consistently twice a week for two months, I saw an enormous difference. It moisturised my scalp and even in that short amount of time, I saw regrowth along my hairline. It kept my hair looking and feeling healthy even after I put it through so much with all the chemicals.
It's given me the confidence to wear my hair tied back as my insecurities around the bald patches have gone. I will continue to use this product and will absolutely be reordering when this bottle runs out.
I see that after 2 months of using it weekly, i start to get more baby hairs!
The bottle is long lasting as you don’t need to use much.
One drop is enough to do your hairline.
I have been using a little on my baby hairs around my hairline. It hasn’t been long but it seems like they’re growing a bit.
There’s no strong scent which is good.
The packaging is nice, I like the curved bottle and the wood. The pipette doesn’t fill up much but that might be the design since a little goes a long way. You just need a few drops.
Leaves my hair feeling so nice! My hair has been very dry recently, but this has made a huge difference, there’s also lots of new regrowth across my head. Definitely worth it (I’m on my third bottle!)
I have been using the hair oil for a while because i noticed my hair thinning due to PCOS ive not noticed my hair getting any thicker but I think it has encouraged some growth on my edges and around my hairline. I think it will help with a bit more time using the product and sticking with it. I have definitely noticed lash growth using the lash oil so I think head hair just takes that bit longer maybe.
I got my hair oil almost to month ago and I already see a difference in my hair. For reference my hair was dry, but with the oil it feel pretty healthy. Very happy and will be buying more when I finish my first bottle.
it's good
I love the brush, haven’t seen much results from the oil and it also leaks. The massager was unnecessary
Great results but wish it wasn’t so expensive
Love the way this oil strengthens my hair
Best oil I ever ordered. Makes my hair soft and manageable
One of the best oils I ever ordered. Makes my hair soft and manageable
Have been using this hair oil for a while now, my hair is so much softer, healthier & has definitely grown. Would definitely recommend!
Although I, for now, continue to have a good amount of hair, I want to be proactive and care for it rather than be reactive once it’s become a possible issue. I didn’t realize how positively receptive my hair would respond to the oil but it seems to really appreciate it. I mindlessly forgot to put it one day and my hair was so much drier; when I use it, my hair is softer and feels lighter. I would definitely encourage you to try it and see how your hair responds.
Can’t recommend this hair oil enough! I love the fact it comes in such a large bottle and it lasts ages! Both myself and my boyfriend have used this hair oil and we both think it’s great! I love the fact that the smell of the oil isn’t overpowering as other oils which I have tried can be like this! Does exactly what it says on the tin! 💕🫶💕
I have been using the hair oil for about 2 months and can see a noticeable difference in my hair growth. I can also see hairs growing back along my hairline!!!!!! Would highly recommend Perl cosmetics
I’ve been using the hair oil for just 2 weeks and I am so impressed with the results! My hair feels less oily, the condition of my scalp has improved; my hair is more dense and is jait growing so quick! I feel like my true feminine self 🩷
I have been using this product regularly since release and after going to my hairdressers she confirmed my hair felt and looked thicker and I had loooooads of new hair growth, I am obsessed, I've tried loads of different hair serums/oils and this is the only one I've gotten a solid result from! Muchos love Perl cosmetics xoxo
I've been using this oil (alongside the comb and bamboo brush to stimulate my scalp) once a week for 9 weeks now. It's definitely helped clear up any red itchy patches on my scalp! I've tried other scalp oils before and nothing has worked until now. In terms of hair growth, I can't see much of a difference yet (some baby hairs coming in maybe) however I suspect that could change if I increased use to twice a week, or I just need to keep using for a longer period of time to notice a change. Overall I'm very happy with the oil and accessories and I will continue purchasing in future.
My hair was coming away in clumps, no doctor or hairdresser could give me an answer only, it may be my age, ok I am no spring chicken but early 60’s I didn’t expect it to be coming out in clumps. Having used other Perl products and been very pleased, as a last ditch attempt, I decided to get some of the Hair Oil. I am amazed as is my hairdresser, after using for a few weeks, there is some soft regrowth appearing. The hair brush is great with no tangle and the massage comb is wonderful, you can feel the difference. An added benefit my hair is so much softer and shiny. Will continue buying and very highly recommended for anyone suffering hair loss.
This oil has been amazing for my hair, it's been feeling dry with the summer sun and the hard water in my area but this oil has made it feel so much softer and healthier!!
I feel like my hair is growing faster too with the hair around my hairline looking more full for the first time in years - I'm in LOVE with this product!!
