✅ What it is

• A treatment shampoo from sebamed designed for very dry, itchy, irritated scalps, especially when there’s dryness, flaking, tightness or redness. The key features:

  • 5 % urea: a high-concentration humectant (moisture-binding) ingredient. 

  • Formulated to relieve itching, scaling and redness symptoms of very dry scalp. Mild cleansing system (sugar‐based surfactants) so as not to overly strip an already dry scalp. 

  • Free from alcohol, parabens, colorants, microplastics in some markets. 

• The product size commonly: 200 ml. Info from multiple EU shops. 

🧪 How it works / Key ingredients

• Urea 5%: Urea is part of the skin’s natural moisturizing factors (NMF). At 5 % concentration it helps bind water in the scalp/hair surface, soften rough/dry patches, and help loosen flaking dry skin.

• Polidocanol (in some markets): a soothing agent to help reduce the sensation of itch. (Mentioned in the EU descriptions: “Polidocanol calms irritated, dry scalp reliably.”) 

• Mild cleansing surfactants (e.g., glucosides, sulfosuccinates) instead of harsh detergents, to avoid further damage to dry scalp barrier. 

• The brand emphasises pH-balanced formulations (many sebamed products maintain pH 5.5) to support the skin’s acid mantle and barrier. While I don’t see explicit statement for this particular variant here, it is consistent with the brand approach. 

🎯 Who it’s for / Intended use

This shampoo is best suited for someone with the following scenario:

• You have very dry scalp (not just mildly dry), perhaps with visible flaking, rough patches, tightness, itchiness, or redness. Example: “dry and itchy scalp” described in many retailer listings. 

• Your scalp is sensitive and you want a gentler cleansing/shampooing option rather than strong anti‐dandruff or anti‐fungal shampoos (unless referred by a doctor).

• You prefer a formula that emphasises moisture and barrier repair (rather than purely oil control or dandruff fungicide).

• If you have dandruff due to oily scalp or fungal overgrowth (e.g., typical greasy dandruff), another variant (like the sebamed “Anti-Dandruff” line) might be more suitable.

• If you have moderate to severe scalp disease (e.g., psoriasis, seborrheic dermatitis, heavy crusting) you may need a medicated/dermatologist-supervised treatment.

🧴 How to use it

From manufacturer/retailer instructions:

• Wet your hair and scalp with lukewarm water. 

• Apply an adequate amount of the shampoo to the scalp, massage gently to distribute. Topics: “Apply to wet hair, massage in gently and rinse thoroughly.”

• Rinse thoroughly with lukewarm water.

• After rinsing, pat dry hair and if you use a hair dryer, use lower temperature setting. 

• Frequency: Depending on scalp dryness/condition, you may start with maybe 2-3 times a week (or more if very dry) and then adjust. The brand doesn’t (in the sources I saw) state a strict “daily” or “every wash” rule for this variant, but consistent use is important.

• Maintenance: Once the scalp condition improves (less flaking, less dryness, less itching) you may reduce frequency or switch to a gentler maintenance shampoo, but monitor your scalp.
