Henna, also known as Mehndi, is a dye prepared from the plant Lawsonia inermis, also known as hina, the henna tree, the mignonette tree, and the Egyptian privet, the sole species of the genus Lawsonia. In ancient times, they were using herbs, plants, mixing them together for thrilling colors to continue to look younger with covered grey hairs. Henna has been one of those items that have been used by many different cultures for countless years.
Even though Henna has been used as a natural product to dye the hair a warm red tone what many people don't know is that Henna is permanent on hair. After lightening a few shades, when henna is finally oxidized, it will remain as it is on your hair until it grows out and is cut off unless chemical bleaching is used. For chemical hair dyes to set, you will need to wait for two to three months after henna dyeing and vice versa, so make sure you are 100% sure to go for it. Unpleasant results of shading cannot be removed so fast.
Due to Henna being a natural product, you cannot predict the exact tone of red you will achieve as the product works with your hair and everyone reacts to it differently. It can go from a very vibrant orange red to a dark burgundy tone.
Henna can also be very drying on the hair, it will not lock out moisture but initially the hair will feel very try and weighed down.
