Best products to grow black hair. When it comes to epilation, ingrown hairs are the most common side-effect. The PFB starts working from the first usage. Mrs Allen February 20, - 1: From Gro-aut Solutions: My concern is will the ingrowth will reduce by using epilator n hope coz of epilator my skin will not become dark in colour. Is it a problem on my end? I am sorry to hear that our product did not work for you, unfortunately you are amongst the few. Although this product gave my hair shine, body and bounce it irritated my scalp. Together, these ingredients stimulate and uphold your hair at the maximum quality it can offer.
