People expect a lot from shampoos. Unfortunately, it is not easy to tell a
good shampoo from a poor one. Cost, fragrance, and lots of foam is
what most people look for in shampoo products. Lather and foam is of
little importance , but they often get the most attention.
This lathering occurs when surfactant molecules gather around air instead of
oil. The result is millions of tiny bubbles. Obviously, the air
bubbles are using the surfactants that should be removing dirt and
oil. We have all seen shampoo advertisements showing happy,
beautiful people taking showers with their heads heaped high with
mounds of lather. These images have taught the public to associate
lather with cleansing ability.
The truth is, lots of foamy lather only means too much shampoo was
used. Excess foam equals waste. Sebum and other oils quickly
destroy foam. Ideally, the head should have just enough lather
to lubricate the scalp and hair. This will help your fingers
massage the shampoo more effectively into the hair.
Fragrances and foaming qualities are not good ways to evaluate
shampoos. Examine the hair's condition after several uses. Is it
flyaway, is it hard to comb, does it seem limp, do colors fade,
is the hair dry or the scalp itchy?
Carefully choose the shampoo to use.
