I shaved my head. What should I put on it to make it brighter?

Make sure there is no stubble ~ ~ ~ Then there is something called butter (extracted from petroleum) or a cosmetic called alum, which is used to wipe your face in winter to prevent dry skin. These two things, the former will clog pores but shine like a mirror, which can be wiped for a short time (one day), while the latter is not so bright (relatively speaking, it will still have a reflective feeling), but it is absolutely harmless to the skin! Choose for yourself. Some people use hair oil (the kind that makes hair).
