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.
My lashes were so short and damaged after years of lash extensions. This lash oil completely changed them! You can see in the photos the amazing amount of growth.

Nothing unnecessary
Apply to dry hair before washing, massaging into the scalp and working through the lengths to the ends using the Wide Tooth Comb. Leave on for at least 20 minutes, or up to 2 hours for a deeper treatment, then shampoo as normal. With regular use, hair looks stronger, shinier and more nourished, and the scalp feels calmer and more balanced.
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.
HAIR OIL
Before you wash, massage most of the oil into a dry scalp, then smooth the rest through your lengths and ends. Leave it on for 20 minutes to 2 hours, then shampoo as normal.
We recommend 2 times a week as part of your wash routine. You can use it before every wash if your scalp or hair feels particularly dry.
We recommend 20 minutes to 4 hours. Your scalp and hair absorb what they need in that time, so leaving it on overnight adds little extra benefit.
No. It's a pre-wash treatment, so it all comes out when you shampoo. If you've used a generous amount, shampoo twice to make sure it rinses clean.
Yes. Because you wash it out, it won't weigh fine hair down. Start with a smaller amount and focus on the scalp and ends.
The formula is fragrance-free and has no essential oils, sulphates, alcohol or parabens. As with any new product, patch test first. Stop using it if irritation occurs.
Hair grows in cycles, so give it time. Most people use it consistently for 8–12 weeks before judging the results. Your hair should feel softer and shinier from the first use.
Each 100ml bottle gives you around 30 treatments. Used twice a week, that's 3–4 months of pre-wash care. Focus most of the oil on your scalp, then smooth what's left through the lengths and ends.
It contains argan kernel oil, which comes from a nut kernel. If you have a nut allergy, check the full ingredient list with your doctor before using it.
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 Hair 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.
LASH OIL
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.
