    MTT assay is an accurate and rapid test method to measure cells in Typically, human hairs grows by an average of 0.2-0.5mm per day. however, as hair loss progresses, the extent to which hairs grow slows down. Therefore, it is important to find growth factors that stimulate hair mother cells.

    MTT tetrazolium, yellow water-soluble, is reduced by succinec dehydrogenase in the mitochondria to MTT formazan, the purple non- water-soluble.

    The 1st results
    When MTT assay was applied as active ingredients extracted from the DAMO Herbal Institute by using human keratinocyte cell, purple color was getting darker as herbal extracts promoted cell proliferation.

    Heral extracts, showing the highest proliferation of the cells, were used in the production of the products.

    The 2nd results
    The analysis of 57 herbal extracts by using the 550nm absorbance. 6 and 7 herbal extracts, showing the highest proliferation of the cells, are used in the production of the products .


    DPPH assay is a test method to find out the antioxidant effect of a particular substance by measuring the elimination of radicals.
    Antioxidant effect refers to the effect of preventing the oxidation. Aging means the oxidation of cells, which occurs when free oxygen radicals attack cells. Removinge the excess of free oxygen radicals is a key to prevent cell aging.

    The 1st results
    According to the DPPH test of the active ingredients extracted from the DAMO Herbal Institute, the more antioxidantpowerful antioxidant capacity is , the lighter purple color is .

    Heral extracts, showing the highest antioxidant capacity, wereare used in the production of the products.

    The 2nd results
    The analysis of 57 herbal extracts by using the 550nm absorbance. 7 and 14 herbal extracts, showing the highest antioxidant capacity, were used in the production of the products .
