Yellow nails can also be caused by frequent painting your nails, and is common in nail polish models, even if they use a base coat. So I'd double down on the notion that you shouldn't get all your medical info from the internet. Still interesting. Now tell me why my nails frequently tear and seem to shred! TELL ME!! 🤬😭😉

All that and you didn't talk about the white spots that can sometimes form in nails? *sigh* As far as I have been told... it is when your body has an excess of calcium.

Your finger nails tell a lot about your health. For example, not having them means you could be suffering from a serious case of pissing off captain Levi.

I have very minor beau's lines because a few weeks ago I had constapatipn bad enough that I vomited what food I put in. So for a week after it started moving, I had to be very careful how much I put in. Horses also get those lines.
so the thumbnail for the video showed white lines in you nail and you didn't say anything about white lines in your nail once in the video? my left big toe has ripples and has since I smashed it really bad years ago at work, guess it's just weird now

Who else checked their nails to find out if somethings wrong.
jumpsteadywill (7 months ago)
Truer words have never been spoken..."Don't get all your medical advice from the internet!", but some is apparently okay...BTW, the internet says in no uncertain terms that everything that you are showing symptoms for is cancer, and certain death...so I would argue that no advice should come from the net...just cat videos and baby pictures...

That dark streak scared me before he mentioned that it's pretty common in people with darker completions. I mean, I'll still mention it to my doctor. But, I'm less nervous
Jaiden Jimenez (7 months ago)
My toenails grow incorrectly, causing constant ingrown toenail on the big toes. After several fixes at the GP, I was sent to have my toes cut open, nail bed removed on one side, and treated with (iirc) Hydrochloric acid, now they grow normally. Just thought that might be interesting.
Ks 412 (7 months ago)
What if i have a vertical ridges on my left big toenail but all the other nails are find & my right foot also? But its just one ? & its kinda yellow at the tip i havent painted my nails a dark color since last year maybe sep or oct.

Yo Hank, Nerdfighter here. Is there any chance you'd allow me to translate your videos and upload them to your show? Many people are intimidated by the medical terms and, well, how fast you talk. So could I? Pretty please? Cherry on top and whatnot?

PichTree (1 year ago)
Yellow nails aren’t baddddd I have them and I just wear too much dark nail polish and nail polish, in general. And don’t freaking white them btw, you will regret ittt. I am like, 12 years old, have a little long nails, and I am very healthy boi.

Éowyn Bates (1 year ago)
So what about when a nail falls off and then regrows back? My pinky and big toe nails have never looked the same since they fell off after loosing them to hiking way back in the day. Will they ever look normal again, or is the damage permanent?

Hermione Says (1 year ago)
This was cool.
MyKayla Hill (1 year ago)
Btw just so people know if you use dark pigmented nail polish and don't use a non-yellowing base coat you can see the tips of your nails change colors. As long as your cuticle growth (new nail growth) doesn't look yellow you should be fine, but start using a proper base coat to prevent yellowing.

I simply Google “GetPlanOnly Com”. My cellulite areas have greatly improved swiftly right after making use of it. I am truly astonished by it. This worked a lot better than I`d ever hoped or expected.
Maureen Cohn (1 year ago)
I was wondering about this cellulite trick “GetPlanOnly Com” (Google it) initially when I first learned about it. I was in need of a solution to my cellulite issue so I gave it a shot. Today, “GetPlanOnly Com” has drastically smoothed away all the unmistakable look of that ugly cellulite from my new, smooth skin. The level of smoothness and softness of my skin have improved. I really like it. Simply search it on Google now.
Patricia Westbrook (1 year ago)
If you are like me, you have most likely used numerous anti-cellulite procedures without any success. Just go to Google and search “GetPlanOnly Com”. This is a perfect product in my case. It has helped me to reduce the cellulite around my stomach and thighs. I am happy in regards to the final results.
