✅ What it is

• It’s a medicated shampoo by sebamed, designed specifically for scalps that are oily and prone to dandruff. 

• Key claims: up to ~95% reduction in dandruff after about 4 weeks of regular use (on greasy hair + visible flakes) when used appropriately. 

• It’s formulated at a pH of 5.5, which matches the natural acid mantle of healthy skin/scalp, which sebamed emphasises as important for scalp barrier health. 

• Additional features: soap-free, vegan formula in many markets; silicone-free and microplastics-free (at least in EU versions) according to listings. 

🧪 How it works / Key ingredients

• Active ingredient: Piroctone Olamine — an antifungal/antimicrobial agent commonly used in anti-dandruff treatments. The product page cites this as the mechanism for reducing dandruff and oiliness. 

• Supporting features:

  • pH 5.5 to support the scalp’s natural acid mantle (helps maintain barrier, reduce irritation) 

  • Formulated to cleanse excess sebum (oil) on scalp + reduce itchiness & flaking associated with greasier scalp. 

  • Free from soap (so less harsh on scalp), vegan in some markets, no microplastics. 

🎯 Who it’s for / Intended use

• People with oily scalps (i.e., hair that becomes greasy quickly) and visible dandruff or flaky scalp. The formula targets both oiliness and dandruff. 

• If your scalp is dry rather than oily, or if the flakes are due to dry scalp rather than oily/greasy dandruff, a different formulation (more moisturizing) might be more appropriate.

• It's positioned for “long-term treatment” of dandruff in greasy/itchy hair rather than just a one-time cleanse. 

🧴 How to use it

• Wet your hair and scalp, apply the shampoo, massage into scalp to work up a lather, then rinse thoroughly. Some instructions recommend repeating if necessary. 

• For best results (based on manufacturer claims) one might need to use it consistently (e.g., a few times a week) over a period of weeks to see the full benefit. 

• Because it’s designed for oily, dandruff-prone scalps, likely you’ll use it maybe 2-3 times/week (or whatever your routine is) until the dandruff is well controlled, then you might reduce frequency to maintenance.

• After rinsing, it’s generally okay to follow with a conditioner if desired (especially on the hair lengths) but for the scalp you may want to avoid heavy conditioners that weigh the scalp down if oiliness is the issue.
