Introduction
Most of us have a cupboard full of half-used hair products. A serum that was too heavy, an oil that made the roots greasy, a spray that promised the world and was forgotten after a week. The problem is rarely a lack of products. It’s that the routine is too complicated, and it’s hard to know how much of anything to use. That’s the gap REHAB. Your Hair set out to close.
REHAB. is a female-founded British haircare brand built around a simple idea: hair oil in pre-measured, single-use capsules. Each capsule holds one dose, so there’s no guesswork, no overpouring and no sticky bottle. In this guide, we look at how to build an easy routine around the brand’s hair oils, which formula suits which hair type, and the styling tools and leave-ins that complete the set. If you’d like to browse as you read, you can explore the full range at REHAB. Your Hair.
1. Why a Simple Hair Routine Works Better
A good routine is one you’ll actually stick to. When you’re juggling several products with unclear instructions, it’s easy to use too much, skip steps or give up altogether. Fewer, better-targeted products tend to give more consistent results.
A simple routine usually covers three things:
- Cleansing and conditioning on wash day
- A leave-in or oil to smooth, soften and protect
- A styling method that doesn’t rely on daily high heat
REHAB. builds its range around exactly these steps, with targeted oils as the centrepiece. The brand describes its products as “innovative, eco-conscious, award-winning” and says it offers targeted oils “for every hair type,” from frizz to fine hair. You can see how the range fits together on the official REHAB. website.
2. What Makes Pre-Dosed Hair Oil Capsules Different
Most hair oils come in a bottle with a dropper or pump, which makes it surprisingly easy to use too much. Too much oil can leave hair looking flat or greasy, particularly if your hair is fine.
REHAB.’s Dose hair oils come as capsules instead. According to the brand, the flagship Dose 1.0 contains 30 pre-dosed capsules filled with a blend of oils and vitamins designed to repair, smooth and protect all hair types. You simply twist or snip open a capsule and use the oil inside.
There’s also a sustainability angle. REHAB. describes the capsules as 100% biodegradable. Once empty, the capsule can be placed in hot water, where the brand says it dissolves easily, and it’s designed to be drain friendly.
Key benefits of the capsule format:
- One measured dose every time, so you don’t overload your hair
- Travel friendly, with no leaking bottles in your wash bag
- Vegan and cruelty-free formulas (Dose 1.0 and 1.1 are both described as vegan and cruelty-free)
- Biodegradable capsules that dissolve in hot water
3. Choosing the Right Dose for Your Hair Type
REHAB. offers several Dose formulas, each designed for a different need. Here’s how the brand describes them:
- Dose 1.0 Hair Oil: a nourishing formula that leaves normal to thick hair feeling softer, smoother and visibly healthier.
- Dose 1.1 Fine Hair Oil: a lightweight, dry-touch oil for fine, short or oil-prone hair, with a sweet almond scent.
- Dose 1.2 Anti-Frizz Curly Hair Oil: the brand’s richest Dose, with 8 oils plus vitamin E and shea butter, designed to smooth frizz, define curls and lock in moisture.
- Dose 2.0 High Shine Finishing Oil: a finishing oil for dry mid-lengths and ends to add shine and tame flyaways.
- Dose 3.0 Sleep Serum Hair Oil: an overnight serum with niacinamide, hyaluronic acid and plant proteins, lavender-scented and suitable for all hair types.
If you’re unsure where to start, REHAB. has a Hair Quiz on its website that gives personalised recommendations. As a rule of thumb, start with 1.0 for normal to thick hair, 1.1 if your hair is fine or gets greasy quickly, and 1.2 if you have curls or battle frizz. You can compare all the formulas side by side on the REHAB. hair oil range page.
4. How to Use REHAB. Hair Oils
Using a Dose is straightforward. For Dose 1.0, 1.1 and 1.2, REHAB. recommends applying the oil to damp ends of hair before styling, daily or as needed.
Some tips for best results:
- Focus on the mid-lengths and ends rather than the roots
- Warm the oil between your palms before applying for even coverage
- If you have extensions, avoid applying oil directly to the bonds or adhesive areas
- Use Dose 2.0 on dry hair as a final step if you want extra shine
For the overnight Dose 3.0, the brand suggests applying it to the lengths and ends of dry hair 1 to 2 nights per week, ideally with your hair in a protective style. There’s no need to rinse it out.
REHAB. also says its hair oils are formulated without parabens and sulphates and are suitable for coloured hair and extensions, which makes them an easy fit for most routines.
5. Adding a Leave-In: The Hair Milk and Hair Moisturiser
Oil is only one part of the picture. If your hair tangles easily or you regularly use heat tools, a leave-in spray can make a big difference.
REHAB.’s Hair Milk Conditioning Heat Protection Spray is a multi-tasking leave-in. According to the brand, it protects against heat up to 230°C, detangles, smooths frizz and locks in moisture for up to 72 hours. You shake it, spray it evenly through wet hair before brushing or heat styling, and can also use it between washes to refresh waves and curls.
REHAB. suggests using the Hair Milk alone or layering it before Dose 1.0, 1.1 or 1.2, depending on your hair type. For drier hair, the newer REHAB. Hair Moisturiser is a lightweight leave-in cream with ceramides, amino acids and plant oils, designed to hydrate, smooth frizz and restore shine.
A simple wash-day order could look like this:
- Shampoo and condition as usual
- Spray Hair Milk through damp hair and detangle
- Apply one Dose capsule to the ends
- Style as normal or set your hair in a heatless curler
If that sounds like the routine you’ve been looking for, you can find your REHAB. leave-in and oil combination online.
6. Heatless Styling with the Silk Heatless Curler
Daily heat styling can take its toll, which is why heatless curls have become so popular. REHAB.’s Silk Heatless Curler is made from what the brand calls the highest grade mulberry silk and is designed to create a bouncy, blow-dry look without heat.
How to use it, according to REHAB.:
- Start with slightly damp hair
- Secure the curler to the top of your head with the claw clip
- Wrap sections of hair around each side of the curler
- Secure the ends with the silk scrunchies
- Leave for 4 hours or more, or sleep in it, then remove
The brand’s top tip is to pair the curler with Dose 1.0, 1.1 or 1.2 for best results. A capsule of oil on damp ends before you wrap your hair is an easy way to combine both steps. If you prefer more volume at the roots, REHAB. also sells Blow Dry Curling Rods for dry or almost-dry hair. Both are available alongside the oils in the REHAB. styling tools collection.
One note for vegan shoppers: REHAB. says most of its products are 100% vegan and all are cruelty-free, but its silk products are not considered vegan because they use natural silk.
7. Bundles, Subscriptions and Saving Money
REHAB. regularly offers bundles that combine oils, leave-ins and tools. At the time of writing, the website lists routine sets such as the Curly Hair Routine and Fine Hair Routine, as well as hydration bundles built around the Hair Moisturiser.
For hair oil fans, the brand runs a subscription called The Dose Delivery. According to the website, subscribers save 30% on hair oil, can switch oils at any time, get free UK shipping, and can skip or pause deliveries. A minimum of 3 orders is required. At the time of writing, the regular price for Dose 1.0 is £26, or £18.20 on subscription.
Promotions change often, so it’s worth checking the homepage before you order. When we checked, the site was advertising a discount code and a free gift with purchase. You can see what’s currently on offer at the REHAB. Your Hair website.
8. Delivery and Returns in the UK
REHAB. ships from warehouses in the UK and Ireland. For UK customers, the brand lists:
- Free standard delivery on orders over £40
- Standard delivery for £4.00 on smaller orders
- Express next-day delivery for £6.00 (order by 9pm the day before, excluding bank holidays)

9. Who Is REHAB. Your Hair Best For?
REHAB. is a good fit if you:
- Want a simple routine without measuring or guessing quantities
- Have frizzy, curly, fine or heat-styled hair and want a targeted formula
- Prefer vegan and cruelty-free haircare
- Like the idea of biodegradable packaging for single doses
- Want to cut back on heat styling with a silk heatless curler
It may be less suited to anyone who prefers a single large bottle of oil to use freely, or who wants an entirely vegan routine including tools, since the silk products are not vegan.
