There's been this black line on my left thumbnail for two years now, and I haven't hurt it or anything. I've been reading stuff online, mostly from Western sites, that talks about what it could mean, but I'm not sure if it applies to me. Is this melanonychia thing common for Indians, especially after they hit 25? And is it usually harmless? What should I be looking out for to know more about what's going on?

Melanonychia, which is the presence of a pigmented band on the nail, can have various causes and can be common in individuals of Indian descent beyond the age of 25 years. In most cases, melanonychia is benign, especially when it is stable over time and not associated with any other symptoms. However, it is important to monitor any changes in the size, shape, or color of the pigmented band. The diagnostic criteria for melanonychia include: 1. Duration of the pigmented band 2. Width and pigmentation intensity of the band 3. Presence of pigmentation in other nails 4. Changes in the nail or surrounding skin 5. Personal or family history of melanoma or other skin cancers It is advisable to consult a dermatologist for a proper evaluation and to rule out any underlying conditions.

After I shave, the skin on my face turns dark green in the shaved area. Barbers say my beard is really tough. What can I do about this? I'm looking for some advice.
The dark green discoloration after shaving, known as pseudofolliculitis barbae or razor burn, can be caused by coarse or curly hair, ingrown hairs, or razor burn; to alleviate this issue, try using a sharp razor, shaving in the direction of hair growth, applying a soothing aftershave balm, exfoliating your skin regularly, and considering alternative hair removal methods like trimming or depilatory creams.
