Purpose

Nourishes the scalp and supports the appearance of healthy, strong and beautiful hair. The formula's varied molecular weights help it penetrate the hair from the cuticle to the inner cortex, supporting healthy-looking hair from the inside out. Suitable for both hair and beard.

Ingredients

8 pure oils — Amla Oil, Argan Oil, Coconut Oil, Castor Oil, Sweet Almond Oil, and essential oils of Lavender, Rosemary and Bergamot. 100% natural, Ayurvedic ingredients. Made in the UK.

The 8 oils in this formula

Amla Oil — Rich in vitamin C and antioxidants. Traditionally used in Ayurvedic haircare to support scalp health.

Argan Oil — Contains a high level of vitamin E, antioxidants and anti-inflammatories, which together support follicle and scalp health.

Coconut Oil — The vitamins and essential fatty acids in coconut oil help nourish the scalp and strengthen the cuticle of the hair, supporting hair that looks and feels healthier and protecting it from environmental factors.

Castor Oil — Rich in protein, which supports hair strength and can help reduce breakage and damage.

Sweet Almond Oil — Its smaller molecule size helps it absorb easily into the hair, creating a sealant on the cuticles that helps lock in the nutrients from the other oils in the formula.

Essential oils — Lavender (traditionally used to soothe the scalp), Rosemary (traditionally associated with hair and scalp care) and Bergamot (a natural aromatic ingredient).

How To Use

As our oil is made up of only 100% pure and natural oil, the way in which you use it depends on your hair type, wash schedule and personal preference!

Roots: Rub 2 pumps of oil with your fingertips and rake/comb through into roots and scalp (do not rub/excessively massage, to avoid manual hair pulling). Use this treatment twice a week and leave it in for a maximum of 1-2 days.

All over hair: Using 2 pumps of oil, rake/comb through your roots using your fingertips. Depending on the length of your hair, apply 3-4 pumps onto the palms of your hand and gently run this through the lengths of your hair. Feel free to use more, e.g. if you have longer/thicker hair. Do this twice a week and leave it in for a maximum of 1-2 days.

Ends: Pour 1 pump of oil into the palms of your hand and rub them together. Push all hair to one side or gather in a bunch and gently press the oil into the ends of your hair. This can be applied daily and left in until you next wash (3-4 days).
Our Story

ByErim Luxury Hair Oil is so much more than just a hair treatment, it’s a symbol of love, legacy, and resilience. After losing her mum to cancer at the age of eight, Erim felt adrift, with no female figures in her life to guide her. She clung to the memory of her mother’s long, beautiful hair, which to her represented strength, beauty, and grace. In her search to feel connected to her mum and to build her own confidence, Erim spent years in her grandmother’s kitchen blending natural remedies. Together, they experimented with everything from onion juice to yoghurt to countless combinations of oils. After a decade of dedication, they discovered the perfect formula: a luxurious blend of eight natural oils that nourish the scalp, strengthen the hair, and honour her mother’s memory.

Every bottle of ByErim Hair Oil carries that love and intention. The formula combines the power of Amla, Argan, Castor, Coconut, Sweet Almond oil and more, infused with the uplifting scents of Bergamot, Lavender, and Rosemary. It’s lightweight, non-greasy, and deeply nourishing  leaving hair soft, shiny, and strong. Erim created it not only for herself, but for anyone who has longed for that sense of care, beauty, and connection. Vegan, cruelty-free, and ethically packaged, this oil is designed to help grow longer, healthier hair while turning hair care into a meaningful ritual one that celebrates where you come from and where you’re going.
