How to use
For best results, use the oil 1–2 times a week, a few days apart.
- Prepare. Start with dry, well-combed hair.
- Apply to the scalp. Using the dropper, apply a measured amount along your partings, directly onto the scalp. Spread it evenly, no need to flood it.
- Nourish the lengths. Smooth a little oil through the lengths and ends for softness and natural shine.
- Massage. Gently massage the scalp for a few minutes with your fingertips or a scalp massager. Skip this step if your scalp is sensitive.
- Leave it on. Leave the oil on for 2–3 hours. Even an hour helps, consistency matters more than time.
- Wash out. Shampoo 2–3 times as needed with the Caroline K Repair Shampoo to remove the oil and complete the routine.
What’s included
100 ml Caroline K Strengthening Hair Oil, to strengthen hair follicles, reduce excess shedding and encourage full, healthy, shiny, longer hair.
Active ingredients
Rosemary oil supports micro-circulation in the scalp and contains compounds studied for their anti-inflammatory and anti-fungal activity. Rosemary has also been linked to DHT-related pathways, although the evidence in humans is still limited. In a small clinical study, six months of using a rosemary preparation improved hair-growth measures, with no significant difference compared with 2% minoxidil. These results do not guarantee the same effect for every oil product.
Castor oil nourishes and softens the hair fibre for healthy-looking, strong, shiny hair. It contains ricinoleic acid, which has been studied for anti-inflammatory and antimicrobial activity. Applying it may help soften the scalp and ease dryness; there is currently no solid clinical proof that castor oil alone stimulates hair growth or treats fungal dandruff.
Pumpkin seed oil is rich in fatty acids and plant compounds that nourish the scalp and soften the hair. It has been studied in relation to DHT-related hormonal pathways and hair density: in a study using an oral pumpkin seed oil supplement, hair count improved by about 40% on average after 24 weeks. Results from taking it by mouth should not be assumed for topical use on the scalp.
Black seed oil contains thymoquinone, a plant compound studied for its antioxidant, anti-inflammatory and antimicrobial properties. It is used to care for the scalp and can help with softness and dryness. Early studies have looked at black-seed preparations and hair shedding, but there is not enough evidence that it reawakens dormant follicles or treats seborrhoea, fungal infections or nutrition-related hair loss on its own.
Tulsi seed extract comes from traditional Ayurvedic practice, where it is known for helping to reduce excessive shedding and support hair growth. It is used to improve scalp circulation, strengthen the hair fibre, reduce breakage, purify the scalp, calm itching and balance sebum.
Brahmi leaf extract is a well-known Ayurvedic ingredient for scalp and hair care. Its saponins and alkaloids help nourish the follicles; massaging the scalp with a Brahmi-based product boosts local micro-circulation, and its cooling, soothing properties help calm an irritated scalp and ease dryness and dryness-related flaking.

Eden –
An amazing product that helps with post-partum shedding, and it smells incredible! Safe while breastfeeding and highly recommended.
Esti –
This oil really changed my hair and my life. After crazy shedding following my pregnancies, it’s the only product that saved me!!!! After two months of consistency I already saw results. No words… a must-have.
Revital Segal –
After my first birth I lost a fifth of my hair, no exaggeration. I started getting really thin areas. A year and a half later, after my second birth, using this amazing oil, I had shedding for a week to ten days. That’s it, and it stopped! I also have loads of baby-hair growth. Such a different experience. I was so anxious about losing hair, and this saved me. A rare product: I’m amazed more people don’t know about it.
Adel Goldstein –
This oil changed my life. My hair had thinned to the point of bald patches. After a while the shedding stopped, and six months later the whole top third of my hair has filled in. I always order an extra bottle in advance so I never run out.
Ariel Nave Sapir –
All I have to say is: don’t hesitate. I still can’t believe how much this product changed my hair, and if someone had told me, I wouldn’t have believed it either. So I won’t say anything except: if you’re reading this, don’t hesitate. Buy it and stick with it. The facts will speak for themselves.
Ariela Noy –
I was really sceptical, but I can’t explain it, something told me to try. After the very first use my hair was so shiny, and the scent made me realise this is different from every oil I’d tried. I kept going, and then the results came. It changed my life. I’m so grateful. I have no words.
Hila –
I honestly didn’t believe it, but I stuck with it because I’d already bought it, and to my surprise, it works. My hair seems thicker. I can really see growth and there’s less shedding. Thank you, Keren.
Dorin Bartel –
A life-changing product. I suffer from alopecia and my hair growth has come back!! It also looks better, I have to say.
Ariel –
I will never doubt what you say again. Full stop. The change in my hair since I’ve been consistent with this oil is something I never even dreamed of. Maybe I did. Yes. Worth every moment and every shekel.
Neta Rachamim –
Before this I mixed quality oils I bought online, a year of persistence and zero results. I tried this oil and within 3 months the whole top of my hair really filled in! I feel it most when I run my hand through it. Can’t wait to see what happens after a year: I’m already dreaming about it.
Osnat Tzarfati –
At first I wasn’t into the idea of dealing with an oil at all. But I stuck with it because I felt there was something about Keren, something real. Three months in, with one or two oil treatments a week, my hair breaks less, is shinier and easier to style, and the whole top of my hair feels genuinely thicker!!! That’s a shock for me. I persisted, but I didn’t really expect it to work. I’m still amazed.
Ella Chen Zion –
I’m 36 and my hairline had started receding at the temples, my forehead suddenly looked bigger and it really got me down. I’ve been doing oil treatments twice a week for four and a half months and there’s so much new growth along my hairline! In the last month it’s really growing back at the temples too. And the funny thing is the new hair is darker, before, my hair had started going grey. I didn’t expect that. I’m still checking I’m not imagining it.
Orly Gadasi –
The first time in my life I’ve written a product review. For six months I mixed oils I bought online and did two treatments a week. Apart from smoother hair, nothing happened: I was still losing lots of hair, and the thin areas at my temples stayed the same or got worse. I contacted Keren, who was so kind to me. It took her about two days to get back to me, the only minus, and looking back I’d have waited two weeks. A few months in with Keren’s oil and I’m amazed: my temples are really starting to fill in, there’s new baby hair, and the shedding dropped significantly after about 3 weeks.
Gabi Rubin –
I wasted half a year mixing oils at home after following someone on Instagram. Mostly I got a calmer scalp and softer hair, the shedding stayed about the same. A colleague recommended this oil. It’s life-changing. I honestly didn’t believe it, but the shedding really dropped and I have loads of baby hair. I’ve been using it twice a week for over two months, and my hair is shinier too. Highly recommend!
Hila Shalem –
I’m in shock!! My hair has never been this full. When I run my hand through it, the whole top section feels one and a half to two times fuller than the underside. I treat it twice a week religiously, leave it on for 3 hours and wash with the Repair Shampoo. I think it’s been about 4–5 months.
