i have an ingrown hair(i think it is anyway), and it looks like its growing along under the skin it looks like a long lump and is darker coloured, it has been growing over the last couple on months, i was told to exfoliate every day and have been using ingrown hair ointments and it would probably come to the surface, but it hasnt come out yet, it looks like its about 1.5cm long now. what should i do???
