This shampoo is for people with a dry scalp that also produces visible dandruff flakes — it's built to exfoliate and moisturize at the same time, rather than just strip away buildup the way a purely clarifying anti-dandruff shampoo would.

It's a home-use, consumer product, not a prescription or salon-only treatment. Because it's discontinued, it suits someone finishing an existing routine more than someone starting a new one.

The reason to pick Phytheol over a plain anti-dandruff shampoo is the salicylic acid exfoliant, which works on flaking at the scalp level rather than just washing loose flakes away, while glycerin and panthenol are there specifically so exfoliation doesn't leave a dry scalp feeling stripped.

Exact leave-on time and weekly frequency for this discontinued formula could not be confirmed from an official source; check your product's printed instructions if available.

1. Apply to a wet scalp and massage in.
2. Leave on briefly before rinsing thoroughly.
3. Avoid contact with eyes; rinse with water if contact occurs.

Pros

• Salicylic acid gives it a genuine exfoliating mechanism for flaking, rather than relying on cleansing alone to remove dandruff.
• Formulated specifically for dry hair, pairing the exfoliant with moisturizing glycerin and panthenol so it's less likely to leave a dry scalp feeling tighter.
• Straightforward, single-step shampoo rather than a multi-product system.

Cons

• Contains sodium laureth sulfate, so it's not a gentle sulfate-free option despite being aimed at a sensitive, flaking scalp.
• Phyto also sells a separate 'oily hair' Phytheol variant, so it's easy to buy the wrong one by mistake — this version is specifically for dry hair.
• Discontinued, so it isn't a long-term repurchase option.
