Have always been a Terrible nail biter all my life - except a side effect of chemotherapy was rock hard nails and a mouthful of ulcers so I had no urge to bite them during cancer treatment and they grew amazingly (bald but with talons 😝 felt like an American eagle).
I’m about a month into no biting again (once chemo was out of my system they went brittle and the urge returned to nibble ) - I’m eating a lot of walnuts which seem to make a difference to nail quality and have trimmed my cuticles and used bio oil on them and they are slowly improving but …. Any tips to keep going and improve the strength ? Are any of the nail and hair supplements worth it?
