MendhikA Herbal Henna : Hair Color:Triple Shifted, Although most people would associate henna’s effect on the hair to dying its color, henna actually plays a number of roles in that part of our body. Henna has been proven to increase the strength of the hair and therefore represents a safe dye that doesn’t permanently affect the health of our follicles. Herbal Henna helps seal the hair cuticle, preventing breaking, and increasing the shine and appearance of the hair. For people suffering from hair loss or baldness, herbal henna also inhibits this from happening.
