I don't know what is it... Lovely cheerful mani :)

Isn't it just because it's a bit moist and/or oily residue from cuticle care and hand care?
The mani is really pretty!

Gorgeous mani love the base colour :-)

I've never seen anything like that before. No idea. Sorry to hear of your pain. Have you tried looking online? Or speaking to a nail tech that you know or even going to your local salon to ask them? Failing that I'd see a doctor as you are suffering.

I'm really sorry I can't offer any insight to what is happening with your nails :( Don't let it get you down, I am sure there will be a way to fix it. Someone will know what is going on! I think Ananka's advice is great, a nail technician will have seen all sorts of nail problems. On the plus side.. Your manicure is looking great, I love the blackheart, it looks really pretty :) <3 xx

I don't know what it can be, but a professional manicurist, who has a lot of knowledge about the nail anatomy I am sure it could give you an answer. First I think you should live your nails to breath and don't use for a while any pigmented polishes. Good luck with it and keep us informed!
Although you painted nails, look great, perfect for V-Day :)

I know what it is!! It's called Onycholysis and means that the nail is actually getting loose from the skin. Meaning "nail loosening".

It is not dangerous and is often self-inflicted due to too much use of nail hardener and other polishes with "formaldehyde" content. Other causes can be picking/ripping/pealing of polish by a stick or by hand or using peel-off-polish-bases.

The tip is to moist regulary, keep the nails short and NEVER use them as tools so they don't get ripped up more than they are. And try using 3-free or 5-free polish (and NO nail harderner during this time) and no nail art glue on them either.

A swedish blogger recently discussed this here because she was affected:

(it's in swedish but you can google translate it)

Hope it will get better <3

Still, beautiful mani too :)

gorgeous mani!

Sorry about your nail! I've had this happen to me before and never really understood what was happening but it usually disappears after a few days by itself. I find that keeping it moisturised and not painting my nails for a few days really helps the healing. Hope it gets better soon!

sorry to hear about your nails! :( I'm not sure what it is but a few of my nails did that over 10 years ago... so now the white tips of my nails are super uneven and I usually keep my nails a bit longer and painted to hide them

hope you can find a way to heal your nails!

lovely mani, can't wait to see your next... after you finish your treatment :D
