hi,

it can buy from Meka shop, its quite expensive but only use a little bit(5 cents volume)
add some water then will make fully bubbles, even use once time u will feel no more oil
and soft hair as before, last time i got in front hair part so sticky, after used, wow!
its really great, pls buy one bottle and try. its cost around $130 (vip can less 10%)
