Amla Powder is an Ayurvedic herb made from the Indian gooseberry (Emblica Officinalis). When added to the mix, it can boost your Henna hair color by darkening the Henna and preventing the indigo from fading, creating cooler hair colors. Amla also can help enhance the dye uptake for problematic roots. You can apply a full treatment of amla to boost your hair's volume and help bring back waves and curls lost from multiple Henna treatments.
