Is Prell Shampoo Good for Your Hair? By Hair Type
Whether is prell shampoo good for your hair depends almost entirely on how oily your scalp is and whether your hair is coloured. It is a strong detergent formula with very little conditioning, so it is a good match for fine, oily, uncoloured hair and a poor daily choice for dry, coarse, coloured or textured hair. For that second group it still works as an occasional clarifying wash, provided you condition properly afterwards.
Key takeaways
- Good match: fine or medium hair, an oily scalp, no colour, a routine heavy in styling product or dry shampoo.
- Poor daily match: coloured, curly, coily, bleached or chemically processed hair, and sensitive scalps that react to fragrance.
- Everyone else sits in the middle, where it works as a fortnightly reset rather than an everyday wash.
- Conditioner is not optional with this formula. A strong cleanse takes the hair's own oils with the product residue.
- If hair snaps rather than sheds, the cleanse is likely too strong for you. Breakage and shedding are different problems with different fixes.
Is prell shampoo good for your hair, or is that the wrong question?
A shampoo is not good or bad in the abstract. It has a cleansing strength, and the only question that matters is whether that strength matches what your scalp produces and what your hair can tolerate. Ask a person with greasy roots and a person with bleached ends about the same bottle and you will get two honest, opposite answers.
So this page answers by hair type rather than by verdict. If you want the background on the formula itself, its history and what is in the bottle, our companion guide to what Prell shampoo actually is and how it is formulated covers that ground. This one is about whether it belongs in your bathroom.
Which hair types does it actually suit?
| Your hair | Verdict | Why, and what to do about it |
|---|---|---|
| Fine, oily, uncoloured | Good match | The cleansing strength matches the sebum production. Use it two or three times a week and condition the mid lengths only, so the roots keep their volume. |
| Medium, normal scalp, uncoloured | Workable | Fine as an everyday wash if your hair feels comfortable air dried. Many people in this group do better using it weekly and something milder in between. |
| Coloured or highlighted | Poor daily choice | Tone fades noticeably faster. Restrict it to a monthly reset, or skip it entirely if your colour is expensive to maintain. |
| Curly or coily | Poor daily choice | The length is already dry by geometry. Use occasionally as a clarifier, then follow immediately with a mask rather than a standard conditioner. |
| Bleached or chemically processed | Avoid as a regular wash | A lifted cuticle loses water fast and needs lubrication more than cleansing power. Occasional use only, always followed by deep conditioning. |
| Sensitive or reactive scalp | Approach carefully | The fragrance load is higher than most modern formulas, and fragrance is a more common irritant than the detergent itself. |
How do you test whether it suits you, without guessing?
There is a test that costs nothing and settles the question in one wash. Shampoo as normal, rinse, apply no conditioner, no leave-in and no oil, and let your hair air dry completely. Then feel the mid lengths.
If they feel clean and normal, the formula suits your hair and the online arguments do not apply to you. If they feel rough, tangly and squeaky, the cleanse is stronger than your hair needs and no amount of conditioner afterwards fully compensates for that. If your roots still feel coated or heavy, the cleanse is too weak, which almost never happens with this particular shampoo. That single test is more useful than any review, because it is a test on your actual head.
Read the result honestly
People often decide a shampoo suits them because their hair looks good after styling. Styling hides everything. The air-dried, unconditioned state is the only honest measure of what a cleanser did, which is why it is worth doing once even though nobody enjoys the result.
What does a strong cleanse do to the hair fibre?
Anionic surfactants work by surrounding oil droplets so water can carry them away. They cannot tell the difference between the styling wax you want gone and the sebum coating your ends that you want to keep, so a thorough cleanse removes both. On an oily scalp that is a net win, because sebum is replaced within a day. On dry ends, several centimetres from the nearest oil gland, it is a net loss that takes far longer to recover from.
Stripped hair also has a rougher cuticle surface, which raises friction between neighbouring strands. Higher friction plus a comb is the ordinary mechanism behind mid-length snapping. This is the most common way a mismatched shampoo does real, visible harm, and it has nothing to do with the follicle.

Is prell shampoo good for your hair if you are worried about hair loss?
Separate three things that look identical in the shower. Hair loss means the follicle has stopped producing normally, as happens in androgenetic alopecia. Hair shedding means the growth cycle has pushed an unusual number of follicles into their resting phase at once, as happens in telogen effluvium after illness, childbirth, surgery or rapid weight loss. Hair breakage means the fibre snapped along its length while the follicle carried on working perfectly well.
No shampoo can cause the first two. There is no route to the follicle from the surface of the scalp and no hormonal action in a cleanser. A shampoo that is too strong for your hair can absolutely contribute to the third. The distinction is visible if you look: shed hairs carry a small pale bulb at the root end, while broken hairs are short, blunt and bulbless and collect on the bathroom shelf rather than in the drain. If you are finding bulbless fragments, the fix is in your routine. If you are finding bulbed hairs in quantity, the fix is not a bottle at all.
How should you build a routine around it?
If the air-dry test says the formula suits you, the routine is straightforward. Wash two or three times a week rather than daily. Apply to the scalp with your fingertips, never your nails, and let the lather running down do the lengths rather than scrubbing them. Rinse until the water runs completely clear, because residue from a strong surfactant is itchy. Condition from the mid lengths to the ends every single wash, without exception.
If the test says it does not suit you but you want a clarifier, use it once every two to four weeks, follow with a deep conditioner or mask rather than a standard one, and use something gentler in between. Our guide to sulphate free shampoo and whether it is really better explains what a milder surfactant system genuinely changes, and how to use conditioner properly covers the conditioning technique that matters most after any strong wash.
What are the sensible alternatives?
If you want the same clarifying effect with less collateral damage, a dedicated clarifying shampoo used fortnightly does the job with a formula designed for occasional use. If you want an everyday shampoo that will not strip, a sulphate free formula is the category to look at, accepting that it will not lift heavy silicone build-up on its own. And if your actual problem is dry, rough hair rather than an oily scalp, the whole clarifying conversation is a distraction from a conditioning one. Our guide to fixing dry hair with a four step routine addresses that directly, and how to take care of dyed hair is worth reading if colour is involved.
Where does Watermans fit alongside a clarifier?
We sell hair care, so weigh our view accordingly, and we would rather say the useful thing than the flattering one. Our range is sulphate free, vegan and made in the UK, built around cutting breakage so the hair you already have stays on your head and the density you have looks as full as it can. That is a cosmetic job and we say so plainly. A strong clarifier once a fortnight and a gentler wash in between is a perfectly sensible pairing, not a contradiction.
Grow Me® Hair Growth Shampoo
A sulphate free daily shampoo for the washes in between a clarifying reset. Fingertips into the scalp, lukewarm water, no scrubbing the lengths.
Condition Me® Hair Growth Conditioner
The step that matters most after a strong cleanse. Mid lengths down, left two minutes, then rinsed cool so the cuticle lies flat.
Masque Me® Hair Growth Mask
A weekly deep conditioner for coloured, coarse or heat-styled hair, and the right follow-up to any clarifying wash on textured hair.
Watermans products are 100% cosmetic and do not treat medical hair loss. Individual results may vary.
When is this a GP conversation instead?
Changing shampoo is the right response to an oily scalp, product build-up, dull texture, fading colour or strands that snap when you comb them. It is the wrong response to a widening parting, a receding hairline, visible scalp at the crown, patches with no hair at all, or a shed that has run past six months. A GP can arrange blood tests for iron, ferritin, thyroid function and vitamin D. Sudden patchy loss, a painful or scarred scalp, or hair changes alongside other unexplained symptoms should be looked at promptly rather than managed from the bathroom cabinet.
Frequently asked questions
Is prell shampoo good for your hair if you have fine, oily hair?
This is the best match of any hair type. A fine, oily scalp needs genuine lifting power, and the squeaky finish that other people complain about is precisely what someone with greasy roots is trying to achieve. Condition the mid lengths and ends afterwards and this pairing works well.
Is prell shampoo good for your hair if it is coloured?
Not as a regular wash. Efficient anionic surfactants lift oil, and the same efficiency carries deposited dye molecules out through a lifted cuticle, so tone fades faster. If you love the cleanse, restrict it to once a month and use a colour-safe shampoo the rest of the time.
Is prell shampoo good for your hair if it is curly or coily?
Rarely as a daily product. Curly and coily strands are drier along their length because sebum cannot travel easily down a twisted fibre, so removing what little reaches the ends leaves them brittle. Used occasionally as a clarifier, followed immediately by a mask, it can still have a place.
Can you use Prell shampoo every day?
For most people, no. Daily use of a strong detergent on hair that is not genuinely oily leaves the cuticle rough and raises friction, which shows up as breakage rather than as anything dramatic. Two or three washes a week is the sensible ceiling, and for many people once a fortnight is enough.
How does it compare with a modern drugstore shampoo?
It cleans harder and conditions less. Most modern mainstream shampoos moved to milder surfactant blends with silicone conditioning built in, so they feel smoother straight out of the shower. Prell trades that immediate smoothness for a more thorough cleanse, which is better or worse depending entirely on what your scalp is doing.
Do I still need conditioner if I use it?
More than usual, not less. A cleanse strong enough to lift silicone and product will also take the hair's own protective oils, so the conditioning step is doing real work rather than being optional. Mid lengths to ends, two minutes, then rinse cool.
Is prell shampoo good for your hair after swimming?
It is genuinely useful here. Chlorine and salt leave deposits that a mild shampoo struggles to shift, and hard water minerals compound the problem over a season. A strong clarifying wash after swimming, followed by a deep conditioner, is a sound routine.
Will it help with an itchy or flaky scalp?
It might help, or it might make things worse, and the deciding factor is the cause. If the itch comes from product build-up, a thorough cleanse clears it. If the scalp is dry, irritated or reacting to fragrance, a stripping wash with a high fragrance load makes it worse. Persistent flaking or soreness is worth showing to a GP or pharmacist rather than experimenting on.
Conclusion
So, is prell shampoo good for your hair? For a fine, oily, uncoloured head it is a genuinely good and cheap choice, and the squeaky finish other people dislike is exactly the result that person is after. For coloured, curly, coily or bleached hair it is the wrong daily tool, and persevering with it produces rough texture and mid-length breakage rather than any dramatic disaster. The middle ground is where most people actually live: use it as a fortnightly clarifying reset, condition properly every time, and wash with something gentler in between. Run the air-dry test once and you will know which of those three groups you are in, which is worth more than any review including this one.
