Younggun.... I tend to agree with Mr.Hair...... I know what you mean by saying that it`s thinning and you don`t like it, but maybe you`re `jumping`ahead of yourself ? Maybe the top/crown might be/look a bit thinner than what you`re used to but that is just normal thinning. I reckon a topper is all you may need if at all for the moment.....even your sides and back there ---well many guys on here would pay you in gold for those!!! I don`t see why you want the `hassle`and expense of wearing and hair-care routine this `early`.... maybe the top thinning is more noticeable to you in a mirror than what the pics show, in which case a topper would suffice..... I`d give my left eye for that amount of hair !! Still, it`s your choice and you can always leave it grow back again if you wish..you have that option, unlike most of us....regards, Paul.
