Rosemary Hair Oil Co., or RHOCo. for short, is a London-based haircare brand built around plant oils. The range centres on hair oils made with rosemary, castor, argan and other botanicals, backed up by shampoo and conditioner, a hair parfum, silk bonnets and simple brushes and scalp massagers. The brand describes its products as vegan and cruelty-free, without sulphates or parabens. It suits anyone who likes the idea of a pre-wash oil routine, or who is already using rosemary oil and wants a ready-made blend in a dropper bottle rather than mixing their own.
As well as its own website, RHOCo. is sold online by retailers including Superdrug, Tesco and Holland & Barrett. The site also has a free tool called TrichoMatch that suggests a routine after you upload a selfie and answer a few questions.

The headline product is the Rosemary Hair Oil Intense Growth Syrup, a 100ml bottle at £34.99. It's a blend of sunflower, castor, rosemary, sweet almond and sea buckthorn oils, and the brand says it won Best Hair Growth Oil at the Marie Claire UK Hair Awards 2026. If you want the oil plus the accessories, the Starter Discovery Kit puts it together with the pure silk bonnet and a silicone scalp massager for £69.99, so you get all three in one order.
The full ingredient list is on each product page, which is worth reading before you buy because opened products can't be returned.
For something smaller, the Hair Rosé Hydrating Parfum is a 200ml hair mist at £14.99, and the Hair Honey shampoo and conditioner duo is £35.98. UK orders go out from a fulfilment warehouse and usually arrive within one to five working days, and the brand ships internationally as well.

How to save more
- The 35% code only works on your first order, so put everything you want into that one basket rather than buying a single item first.
- Before you buy a bundle or set, add up the individual prices of what's inside, so you know whether the bundle actually saves you anything.
- If you collect points at Superdrug, Tesco or Holland & Barrett, check whether they stock the product you want, as you may get points on top.
