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
Test results - psoriasis/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.
Therefore natural ingredients used in the shampoo bar (Pongamia glabra and Polygonium tinctorium) work better than chemical ingredients for sensitive scalp, dermatitis (psoriasis, eczema) and dandruff.
Solid shampoo for sensitive scalp
Here are things to verify in a shampoo for sensitive scalp :
- pH of 5.5 ✅
- alcohol and essential oil ❌
- perfume ❌
- chemical keratolytic agents (urea, salicylic acid) ❌
- natural stress inhibitors (pongamol) ✅
- natural anti-inflammatory agents and natural fungicides (indirubin) ✅
Presque tous les shampoings antipelliculaires, pour le psoriasis ou l’eczéma contiennent l’un de ces ingrédients (salicylic acid, piroctone olamine, corticostéroïdes), mais aucun n’est utilisé dans notre shampoing ! Nous utilisons des molécules naturelles reconnues pour leurs propriétés anti-stress et anti-inflammatoires.
