Does your hair feel heavy, dull or coated even right after a wash? Do styling products, oils or hard water seem to sit on your hair and refuse to rinse out? You may not need a new shampoo every day. You may need a clarifying shampoo once in a while. This guide explains what a clarifying shampoo is, how it differs from your regular shampoo, when to use it (and when not to), and why salons use one before professional hair treatments.
What is a clarifying shampoo?
A clarifying shampoo is a deep-cleansing shampoo made to remove build-up that regular shampoos leave behind. Over time, hair and scalp can collect layers of:
- Styling products such as serums, gels, sprays, creams and dry shampoo
- Hair oils and leave-in conditioners
- Excess sebum (the scalp's natural oil)
- Minerals from hard water
- Pollution, sweat and dust
A regular shampoo is designed to be gentle enough for frequent use, so it may not remove all of these layers. A clarifying shampoo gives hair and scalp a "reset", leaving a fresh, clean base that your conditioner, mask or salon treatment can work on properly.
Clarifying shampoo vs regular shampoo
- Purpose: a regular shampoo is for everyday cleansing. A clarifying shampoo is an occasional deep cleanse.
- Cleansing strength: a regular shampoo is milder and often adds conditioning or care benefits. A clarifying shampoo is stronger and focuses on removing residue.
- How often: you can use a regular shampoo 2–4 times a week, depending on your hair. A clarifying shampoo is usually used once every 1–4 weeks, or before a salon treatment.
- Afterwards: always follow a clarifying wash with a conditioner or hair mask to restore softness.

Signs your hair needs a clarifying wash
- Hair looks dull and flat, even when freshly washed.
- Hair feels waxy, sticky or coated, or tangles more than usual.
- Your roots get oily quickly and volume disappears within a day.
- Your usual conditioner or mask doesn't seem to work any more.
- You use a lot of styling products or hair oil.
- You live in an area with hard water. See hard water and hair.
- You swim often or spend long days in pollution and sweat.
Why salons clarify before professional hair treatments
If you have had a keratin, cysteine or protein treatment, your stylist almost certainly started with a clarifying wash. There's a good reason for this. Treatments such as Kera Bliss Kera-Plex, Cys Bliss Cysteine and Silk Bliss Protein Re-Filler work best on hair that is completely clean. Oils, silicones and product residue can form a barrier between the hair and the treatment and lead to patchy or shorter-lasting results.
That is why Orangewood's Complete Treatment Line starts with Derma Pure Clarifying Shampoo, a salon-professional clarifying shampoo that removes build-up, excess oil and impurities, so the treatment that follows can do its job. To understand the treatments themselves, read keratin vs cysteine treatment and what is a protein re-filler treatment.

How to use a clarifying shampoo correctly
- Wet your hair thoroughly with lukewarm water. Warm (not hot) water helps loosen oil and residue.
- Apply to the scalp first. Massage a small amount into the scalp with your fingertips, not your nails, for 1–2 minutes.
- Work the lather through the lengths, focusing on areas where you apply oil or styling products.
- Rinse well, then repeat once if your hair has heavy build-up or oil.
- Condition every time. Deep cleansing can leave hair feeling squeaky and dry, so follow with a conditioner or hair mask on the mid-lengths and ends.
- Finish with a serum if your hair tends to frizz. A few drops smooth the ends and add shine.
How often should you use a clarifying shampoo?
- Oily scalp or heavy product use: once a week.
- Normal hair: once every 2–3 weeks.
- Dry, curly or fragile hair: once a month, followed by a rich mask.
- Before a salon treatment: as your stylist advises. It's usually done in the salon as the first step.
Use your regular shampoo for the other washes. For a full wash schedule, see how often you should wash your hair.
When NOT to use a clarifying shampoo
Clarifying shampoos are powerful, so timing matters:
- Right after a keratin or smoothing treatment: deep cleansing can shorten how long the results last. Use a gentle, treatment-friendly shampoo instead. See how to maintain keratin-treated hair.
- Right after colouring: frequent clarifying can make colour fade faster. Wait at least 1–2 weeks and use it sparingly. See our hair colour care guide.
- On a sensitive, broken or irritated scalp: if you have redness, cuts, severe itching or a scalp condition, ask a dermatologist before using any deep-cleansing product.
- As your everyday shampoo: using it daily can leave hair dry and rough. It's a periodic reset, not a replacement.
What to use after clarifying
A clean base is the perfect moment for nourishment. After a clarifying wash:
- Dry or damaged hair: follow with a repairing mask such as Mane-A-Tame Repair Rescue Mask.
- Treated or frizzy hair: use Infudra Mask D'Affluence for a salon-style hair spa finish.
- Everyday balance: go back to a gentle daily shampoo and conditioner such as the Bubble Bliss range.
Frequently asked questions
Is a clarifying shampoo the same as an anti-dandruff shampoo?
No. A clarifying shampoo removes build-up and excess oil. An anti-dandruff shampoo is formulated to help manage flakes and an itchy scalp. If dandruff is your main concern, read our dandruff guide.
Will a clarifying shampoo damage my hair?
Used occasionally and followed by conditioner, a clarifying shampoo is a normal part of good hair care. Problems usually come from using it too often or skipping the conditioning step.
Can men use Derma Pure Clarifying Shampoo?
Yes. Derma Pure is suitable for men and women, and is especially useful for anyone who uses gel, wax or hair oil regularly.
Should I clarify before a keratin, cysteine or protein treatment at the salon?
Your stylist will usually do it as the first step of the service with a professional clarifying shampoo. Don't use heavy oils or masks on the day of your appointment unless your stylist tells you to.
How do I know it worked?
Your hair should feel lighter, look shinier, and your conditioner and styling products should work better. If your roots stay oily for longer, that's a good sign too.
The bottom line
A clarifying shampoo is the reset button of your hair-care routine. Use it every few weeks, or before a professional treatment, to remove build-up, then always follow with conditioning care.
