I have a soft spot for haircare that explains what it is trying to fix. REHAB Your Hair takes that approach with targeted oils, unit-dose capsules and routines built around a particular concern, rather than asking everyone to use the same glossy serum. I looked at the range, the product details, the prices and the customer feedback available on the brand site to work out whether the concept is genuinely useful or simply well packaged.

The headline idea is appealing: choose an oil according to your hair type or finish, then use a measured capsule instead of guessing how much product to pour into your palm. The brand also presents itself as female-founded, eco-conscious and focused on award-winning innovation. Those are worthwhile claims, but they need to translate into a routine that feels easy and not overly expensive.

What stood out in my research

• Targeted formulas: the Dose system separates fine, curly, scalp and shine needs.
• Pre-measured capsules: a tidy way to control portions and reduce bathroom clutter.
• Plastic-free ambitions: the brand highlights biodegradable oil capsules and a plastic-free Vital Hair Brush.
• Head-to-toe range: hair, scalp, body and lip products make the shop broader than a single oil line.

That targeting is the strongest part of the proposition. If you have fine hair, a rich oil can quickly make roots look flat. If you have curls, the same formula may not give enough slip or frizz control. A range that acknowledges the difference is more practical than a one-size-fits-all promise. The site also offers a hair quiz, which is a useful starting point if you cannot decide between the product options.

The products I would actually compare

The most sensible entry point is REHAB. Dose 1.0 Hair Oil Capsules, listed at £20.80. The capsule format suits someone who wants a small, consistent amount for lengths and ends. My pro is control: it removes the usual slippery guesswork. My con is flexibility: one capsule can feel like a lot on very short or very fine hair, while thick, long hair may need more than one.

For textured or frizz-prone hair, REHAB. Dose 1.2 Anti-Frizz Curly Hair Oil is the more obvious experiment, also priced at £20.80. The name makes its use case clear, and I like that the range does not treat curls as an afterthought. It should be worked through damp hair in a light layer, with extra care around the ends. If you want a curl-specific option, you can see the current Dose 1.2 details before committing.

For a polished finish rather than a treatment-led ritual, REHAB. Dose 2.0 High Shine Finishing Oil is listed at £20.80. This is the one I would choose for smoothing a blow-dry, softening dry ends or adding a final reflective touch. The trade-off is that a finishing oil cannot repair split ends, and too much will make hair look coated. The Dose 2.0 product page is worth checking for the latest instructions and stock status.

There is also a scalp-focused angle. REHAB. Matcha Scalp Serum is listed at £24.00 and makes sense for someone whose main complaint is the scalp rather than dry lengths. That distinction matters. An oil on the ends and a scalp serum are not interchangeable steps, so I would not buy both without a clear reason. You can review the Matcha Scalp Serum details alongside your existing wash routine.

How I would use the range

1. Wash and condition as normal, then towel-dry without rough rubbing.
2. Choose one targeted product for the job you actually want to address.
3. Start with a small amount through the mid-lengths and ends, avoiding the roots unless the instructions say otherwise.
4. Wait until the next wash before deciding whether the formula is too heavy or too light.

This staged approach is important because the biggest weakness of a specialist range is temptation. It is easy to add an oil, a serum, a milk and a styling product at once, then have no idea which one helped. I would test one change for a few washes. That gives you a more honest read on softness, shine, frizz and manageability than a dramatic first-day pile-on.

The honest pros and cons

• Pro: the product names make choosing by concern unusually straightforward.
• Pro: £20.80 for a capsule oil is a manageable trial price compared with a large luxury bottle.
• Pro: the brand has a coherent eco-conscious story across capsules, tools and refill-minded routines.
• Con: capsules may be less convenient for people who want to adjust their dose precisely.
• Con: targeted products can become an expensive collection if you buy without a specific need.

The evidence is strongest at the level of range design and customer usability. The official site displays substantial review counts on several products, including ratings above four stars for the oils, while the wider brand profile shows 4.7 out of 5 on Trustpilot from more than 4,000 reviews at the time of checking. That is encouraging, but it is not the same as an independent clinical test. I would treat the results language as a reason to try a product, not a guarantee of hair growth or damage reversal.

Who should try it?

REHAB Your Hair is a good fit if you like a guided routine, want to match a product to your hair type and prefer smaller controlled doses. It is especially interesting for people who find traditional hair oils too vague or too easy to overuse. The concept is less compelling if you already own a dependable oil, dislike single-use packaging, or expect an oil to solve structural damage on its own.

My pick would be the product that maps most closely to your complaint: Dose 1.0 for a simple oil trial, Dose 1.2 for curls and frizz, Dose 2.0 for a glossy finish, or the Matcha serum when the scalp is the priority. If you are shopping for a broader routine, the Fine Hair Routine is the more involved route, but I would start smaller unless you already know fine hair is your concern. Compare the routine options before adding multiple steps.

Overall, this is a considered haircare range with a genuinely useful organising idea. The prices are not bargain-basement, but the capsule format and clear use cases make the first test less intimidating. The limitation is proof: the claims and reviews are promising, yet the best evidence for you will be how one carefully chosen product behaves on your own hair.

Verdict: REHAB Your Hair earns a cautious recommendation for its targeted, easy-to-test formulas, provided you buy for a specific need rather than the whole shelf.
