HOIA Hair Growth Serum
Balance. Nourish. Restore.
This carefully crafted hair serum blends botanical and essential oils to support scalp health, encourage natural hair growth, and restore shine and vitality. Lightweight yet deeply nourishing, it replenishes hair with essential fatty acids while softening, smoothing, and strengthening from root to end.
Designed as a scalp-focused ritual, the serum helps relieve dryness, irritation, and itching, creating a balanced environment where healthy hair can thrive. At the heart of the formula is black cumin oil — a powerful botanical known for supporting hair growth, helping reduce hair loss and premature greying, and protecting both scalp and hair with antioxidant care.
Awarded the Beauty Favorite Award (2019), this bestselling serum has become a trusted favourite for those seeking stronger, healthier-looking hair.
How to Use
Apply the serum to the scalp and hair roots, then gently massage for 5 minutes. Leave it on for 20 minutes before washing it out with shampoo. If needed, follow with conditioner.
For hair growth restoration, use 2-3 times a week. This versatile serum can also be applied to hair ends as a mask or added to a hair balm for extra nourishment.

Really good for calming a dry scalp. Washes out easily and doesn’t make roots greasy. Maybe I’m imagining it, but I feel like I even have fewer grey hairs 😀 — and it definitely adds shine.

I’ve been using this for years and my hair really benefits from it. It makes hair soft and easy to brush, helps with hair loss, and supports new growth.

Definitely recommend if you struggle with a dry, flaky scalp. It cooled and moisturised right away, and most of the dandruff-like flakes disappeared after the first use.

An incredible product!
I’ve struggled with hair thinning for two years and tried so many things without success. After using this for three months, I can honestly see a difference. Baby hairs are coming in, and my hair feels softer and easier to brush. Amazing!

Such a great product. I struggle with a dry, itchy scalp and after one bottle things already feel much better. My hair is softer, shinier, and no longer dull. Love the scent too. Will keep using and highly recommend!

Such an amazing serum. I bought it because of the reviews and I’m beyond satisfied. My naturally curly, usually dry ends were soft and hydrated after the first use. This serum is definitely staying in my routine. And the scent is incredible!

This serum has made a huge difference for my dry scalp. I usually deal with bad dryness, itching, and major hair loss every winter, but since using HOIA’s serum, the problem has nearly vanished.

eaves bleached hair soft and silky. I haven’t achieved this kind of result even after a salon visit. Very satisfied and highly recommend. Washes out easily.
