Two best friends, a kitchen table and a tiny capsule of hair oil. Three years later, REHAB. is in Selfridges, Boots and Harrods, and Stacey Solomon owns a third of it.
If you've spent any time on Stacey Solomon's Instagram, you'll have seen the little dissolvable capsules. They belong to REHAB., the British haircare brand that has quietly become one of the most talked-about names on the bathroom shelf. It's vegan, cruelty-free and built around one clever idea: the right amount of hair oil, every time, in packaging that disappears in hot water.
The story
How two busy mums built a cult haircare brand.
REHAB. was founded in 2022 by best friends Vicky Ellis and Anastasia Tozer. They are both mums and had each spent more than 15 years in the beauty industry. Like most of us, they were juggling jobs, children and social lives, and they wanted haircare that was effective, easy and kinder to the planet. Vicky had spotted a gap in the market for affordable, salon-inspired products that focused on repair. The answer was Dose 1.0: a pre-measured hair oil sealed in a biodegradable capsule. You twist it open, smooth it through your lengths, then drop the empty capsule into hot water and watch it dissolve.
The early days were properly scrappy. The brand has said it was packing orders from kitchen tables and garages, and it has been self-funded from the start, putting its profits back into the business.
Then, in October 2023, came the news that put REHAB. on everyone's radar. Stacey Solomon had been a loyal customer, and she announced that she had invested in the business and become a co-owner. She told her followers she was now a third owner of the brand. It was the first business she had personally invested in, and she described it as the start of a new chapter spent championing women in business. For a female-founded brand run by two mums, it was a perfect fit.
The growth since has been extraordinary. REHAB. has reported a 5,030% increase since launch. It has been profitable year on year, and around 70% of customers come back for more. The range has grown from a single oil to more than 70 products covering haircare, bodycare and, from 2026, skincare. It is now stocked at Harrods' H Beauty, Selfridges, Boots and Sainsbury's. In early 2026 it opened its own Prescription Bar in The Beauty Spot at Selfridges, the first haircare brand to take a space there.
Prices are usually mid-range, with the signature capsules at £26 a bottle. As we publish, though, REHAB. has 50% off sitewide plus a free Rescue Ritual Set with every order until 30 November, so it's a very good moment to try it or stock up on Christmas presents. Here's our edit.
