Hi, It is very difficult to get thanaka powder here in India and i really don't knw how much it is effective. But you can try Vacha/ vekhand powder for hair removal. Take 1portion of Vekhand powder and add 1 portion of
Sugar powder add little amount of water make a paste & apply it where u have unwanted hairs. But u hav to apply this paste daily for 3-4 months. Plz don't apply it on delicate area. And plz go through all hormonal check up if u have excessive hair growth.
