Behind the Science
Behind the Science
Stimulating the scalp.
Rosemary and peppermint oils are among the most-studied botanicals in hair care, valued for supporting circulation at the scalp. Better blood flow means follicles are better supplied with the oxygen and nutrients active growth depends on which is why scalp massage with these oils is a long-standing practice.
Strengthening the strand.
Castor oil and pumpkin seed extract are nutrient-dense and traditionally used to support hair strength and density. Pumpkin seed, in particular, has drawn research attention for its role in hair health, while castor oil's fatty acids help condition and protect the strands against breakage.
Calming the environment.
Healthy growth needs a healthy scalp. Aloe vera, lavender, and lemongrass soothe and help balance the scalp, easing the irritation and inflammation that often accompany thinning and can make a stressed scalp worse.
Protecting against damage.
Vitamins C and E are antioxidants that help defend hair and scalp from the oxidative stress that contributes to weakening over time, while olive oil adds lasting nourishment and moisture.

How to Use
Start with a dry or damp scalp
Apply to clean hair for best absorption. No need to wash beforehand; just part your hair to expose the scalp.
Apply directly to the scalp
Part your hair in sections and apply the oil along each part, focusing on areas where you notice thinning or shedding. A few drops per section is enough.
Massage thoroughly
Use your fingertips to massage the oil in gently. This boosts absorption and stimulates circulation at the follicle, where healthy growth begins.
Leave in and style as usual
The oil absorbs like a serum, so there's no need to rinse. Style as normal, morning or evening.
Repeat daily and stay consistent
Use once daily for best results. Hair grows in cycles, so consistency over an 8–12 week window is what drives visible change.
Tip
A little goes a long way; a 60ml bottle lasts most routines around six weeks of daily use. For an extra boost, apply before bed and let it work overnight.

Frequently Asked Questions
Both treatments work on the same principle, supporting your scalp and follicles through your hair's natural growth cycle, but they're built for different routines. Hair Activator Oil is the lightweight daily option: a serum-like scalp oil with a focused blend of stimulating actives like rosemary and peppermint, designed to absorb cleanly and fit into your everyday routine. It's the ideal starting point for maintenance and for getting ahead of early thinning.
Hair Regrowth Treatment Advanced is the intensive step up. It carries over those same scalp-stimulating actives but layers them into a far more concentrated complex of 20+ Ayurvedic-inspired botanicals: amla, bhringraj, fenugreek, and more. Richer by design, it's used as a deeper treatment a few times a week rather than daily, making it the choice for more demanding concerns or for anyone who wants the most potent version of the Hairylin approach.
The simplest way to think about it: the Activator Oil is your daily maintenance, the Advanced is your intensive treatment. Many people use both the oil for everyday consistency and the Advanced as a weekly deep treatment for a complete routine that works your hair's full cycle.
Tip: Pair with Hair Activator Oil for a complete routine: the daily oil for everyday maintenance between Advanced treatments. Patch test before first use, as this is a concentrated botanical formula.
We recommend using our regrowth oil 3x a week for 3 continuous months to see the best results. That said, you may experience benefits after just a few uses, including a happy scalp, more hydration, and less product buildup.
Used as directed: a few drops massaged into the scalp, not the lengths; it absorbs without weighing hair down. If you have fine hair or prefer a lighter feel, apply in the evening and wash in the morning, or use every other day.
We recognize that some users have more sensitive scalps than others. You will still have the same benefits of applying our hair oil whether there is a tingly feeling or not. Some users report a more pronounced tingly feeling if they use the serum immediately after showering on clean, damp hair, so that may be worth a try!
If you notice any unusual symptoms, stop using the product immediately and consult your doctor.
Yes. Since the oil goes on your scalp and most stylers go on the lengths, they don't compete. Apply the oil first, let it absorb for a minute or two, then style as usual.
Keep oil and direct heat separate. The oil isn't a heat protectant, so apply it on non-styling days or overnight, and use a dedicated heat protectant on your lengths on styling days. As a scalp treatment, it fits easily into your week without overlapping.
A 60ml bottle lasts most routines for around 4 weeks of daily use.
Yes. The formula is plant-based with no harsh chemicals and includes aloe, lavender, and lemongrass to soothe and balance the scalp. As with any new product, patch test first if you have known sensitivities.
Most routines show meaningful change over an 8–12-week cycle, in line with your hair's natural growth timeline. Consistent daily use is key.
Yes! Our products are formulated for all hair types and textures.
While our oils are not a cure for conditions such as alopecia areata, they are formulated to enhance scalp circulation and provide intense nourishment over time.
