Skin, Hair and Nail Problems

I have back acne since many years now.. I dont remember when it started but its getting bad now.. My full back is full of acne & dark stubborn acne spots and lots of red spots.. I also have oily skin overall.. How to get rid of it?

My two hair strands starts greying.       What should i do to avoid spreading of hair being grey...?

Dear doctors. My husband during winter white patches comes on face. What can be resolution for the same. His skin is dry. Whit patches on face.

I have found in my foot one place is hard inside and it is pain but I don't know what is is.. please suggest what should I do.

I am 28M working professional. I have very bad diet habits , I consume less vegetarian foods. I had lot of acne breakouts in past, I couldn't consult a doctor as the acne always went away in few weeks. Eventhough the acnes went away, they left behind acne scars and now that I look at the mirror, I find many scars on my face. After a quite extensive research on google, I found out that I had all the types of scars:boxscars (approximately 4) , toothpick scars(approximately 3), blemishes and what not. I think I have few active acne as well.  Google suggests various surgical procedures like microdermabrasion, chemical peels that needed to be done by a professional multiple times to get better results. I am not willing to undergo any of the surgical procedures at the clinic. I just want to know if these acne scars can be reduced significantly with over the counter doses/ointments. Also, if there are over the counter doses, please let me know in how many days I can expect to see results

I have wavy, dry and frizzy hair... can I use leave in conditioner to control frizz and can someone please suggest a good leave in conditioners coz most of em cause hairfall

I got this ring mark on my leg since past 2-3 months now. It sometimes itches. I take medicine for thyroid and no other problem is there.

I have a small lump under the skin in the cheeks. It's not popping out. When I touch it. It feels hard.

I have keloids, & took steroids also But it didn't impact on me much So please suggest me what treatment I can take & proceed further. Thank you!
