This shampoo is formulated for people with an oily scalp or oily roots who need help regulating sebum production, regardless of hair length or texture. It suits anyone new to a purifying-shampoo routine as well as those already used to clarifying formulas.

It is a consumer retail product sold through pharmacies and beauty retailers, not a salon-exclusive treatment, so it can be used at home without professional supervision.

The reason to reach for Phytocedrat over a general-purpose shampoo is its narrow focus: it's built to interrupt the cycle of an oily scalp producing more oil, rather than just cleaning hair for the day. Citron peel oil and plant-derived surfactants cut through excess sebum without the stripping effect of sulfate shampoos, while sage, nettle and tormentil extracts are included to support scalp comfort during that process.

Apply Phytocedrat to wet hair and scalp.

1. Massage gently into the scalp to work up a lather.
2. Leave on for about 2 minutes.
3. Rinse thoroughly with warm water.

Pros

• Sulfate-free cleansing base (sodium lauroyl sarcosinate, cocamidopropyl betaine) is generally milder on the scalp than harsher sulfate surfactants while still cutting through oil.
• Formulated specifically to regulate sebum rather than just mask oiliness, which can let you stretch time between washes.
• Short 2-minute contact time makes it easy to fit into a normal shower routine.

Cons

• Contains added fragrance (parfum), a consideration for anyone with scalp fragrance sensitivities.
• As an oil-control formula, it isn't designed to add moisture, so it may be too drying if used on dry or chemically treated lengths.
• Contains synthetic preservatives (phenoxyethanol) and a conditioning polymer (polyquaternium-22), so it doesn't qualify as a natural or organic product despite the plant extracts.
