Don't laugh. This stuff REALLY works--but only if you just have a
small spot to cover. Forget it if you don't have any hair that can
be combed over your spot and still look natural; in that case, it
will just look like you painted your head! Cost: $5.00 per can at
some retail stores; $19.95 plus 4.95 shipping and handling (for a
larger can) when sold on late-night infomercials. Several brands are
available. The one called Instant Hair Plus is a good one.
(a) Advantages. If you just have a small spot, this stuff has you
covered. Its odd texture somehow creates the appearance of full hair,
but only when mixed with a sufficient amount of your own thinning
hair.
(b) Disadvantages. The powder might come off on your pillow, shirt,
and hands. Get used to ring-around-the-collar. The better types
come off only when mixed with water and soap. You need to apply
for spray every day, or after you wash your hair. Spray-on hair is
hardly a long-lasting solution, only a stop-gap measure. Eventually,
you won't have enough real hair to make it work.
Alternative: Try Clairol Loving Care Hair Color Mousse (all colors
available) (about $6.00). Smear some of it on a plastic bag and rub
it full strength over your (small) spot and mix it with existing hair.
The effect might be the same as spray-on hair, and, when dry, the
mousse does NOT readily come off on pillows. Once again, this works
only on small spots and in combination with at least some real hair.
