The exact cause of psoriasis or seborrheic dermatitis is unknown.

Certain environmental factors trigger dermatitis and psoriasis.

One of the environmental triggers is shampoo (Trüeb, 2007)!

Irritation potential of surfactants

Solid shampoo - psoriasis and seborrheic dermatitis

The result at 35 days (above image) may seem longer than studies that investigated synthetic keratolytic shampoo (Massiot et al , 2023 ) and corticosteroid-containing shampoo (Griffiths et al , 2006) giving almost similar results at 21 days and 28 days respectively.

But in these studies, the shampoos were used daily, while the Melo Ayurveda Sensitive Scalp Solid Shampoo was used three times a week.

Additionally, our voluntary studies and customer reviews prove its effectiveness for psoriasis and seborrheic dermatitis.

Solid shampoos with natural active ingredients could be a potential topical treatment for dermatitis and dandruff.

 Here are 5 things to check in a shampoo or solid shampoo:

1. shampoo with a milder surfactant (lower zein value)
2. shampoo with a pH of 5.5
3. shampoo without synthetic ingredients (phenoxyethanol/alcohol for example) or natural ingredients (essential oil is a controversial natural ingredient)
4. shampoo without perfumes and its derivatives (for example: linalool)
5. presence of keratolytic agents (urea, salicylic acid), natural stress inhibitors (pongamol), natural anti-inflammatory agents and natural fungicides (indirubin)
