Nowadays the henna cone contains some chemicals, so if you are allergic or your skin is sensitive, then check a little amount of henna on your palm before making the whole design. If it gives you itcy or burning feeling, do not use it. Sometimes, it happens when the henna is expired so make sure to use the fresh one.
Also, if you have done waxing on an area where you are going to apply henna, do not do it just after waxing. Wait a day or two, as skin pores will be opened and henna contains some chemical. This situation may cause damage or irritation on your skin.
Henna gives different color on different skins. On palms, the color is darkest, near to black sometimes. On the other side of hand, the color is much lighter and then on arm it gets lighter. The color comes best after one or two days. You will notice the difference of the color everyday, first it goes darker, then after few days, it goes lighter and finally its gone!
