My son started nail biting around the age of 9. He is16 and ended up biting the cuticles or picking them with fingers. He took most of top of his finger skin off that now has blisters. His middle finger nail is white and bumpy and other 2 are not smooth they have ridges!!!
I have tried stop & Grow liquid for few years but in vain.
I am so worried about his damaged nail.
GP said to ask him to stop biting his nails nothing more he can do for him
