Any Manicurist ?

Just wondering why are my nail beds so small/short and thin?

I’m 22 years old. I feel like it’s always been like that ever since...

whenever I compared my nail beds with my friends (girls), they’re in awe because of how tiny they are (especially my pinky). Also, is it normal to not have the lunula on my fingernails? *only on both of my thumbs, and I used to have them as a kid but it’s gone....

Also, never got my nails done at the salon before. I had painted my nails at home and put those stick - on faux nails when I was kid...pretty much it....

Any explanation or thoughts about it... I’m not concerned just curious... hahah
