i took a deal for hair smoothening for my sister in 1899 but when i reached their they were asking for 1000 Rs more for removing the color of heena frm hair. And the chemical they used , there happened severe hair fall, and they burnt her hait of around 2 inch diametre on her scalp. which we came to know after 3 days when my sister had her hair wash.
its has been a horrible experience. I would not recommend this to anyone.
