Dry shampoo. How does it work?
Well they say it can instantly save you from a bad hair day, but most of us probably don’t know how it works. Not to worry! You really don’t have to be a scientist to understand that dry shampoo combats the oiliness using absorbent ingredients used in the formulation.
Most dry shampoo formulas contain silica, which is an absorbent powder acting like a sponge. Once applied to hair those little sponges absorb the oils and dirt, which results in them becoming higher in density and heavier, and they can be brushed off, leaving a clean surface behind. Another spongy powder is aluminium starch which adsorbs moisture
Some ingredients in dry shampoo may be avoided such as Talc and aluminium starch octenylsuccinate. It’s because they may be linked to some health conditions. For that reason, some manufacturers use natural rice starches instead.
How to use dry shampoo
There are so many dry shampoos on the market to choose from, but we believe that a successful application is more about “how much dry product” than “which brand.” Obviously fine hair only requires a light application of the product while anyone with thick or coarse hair will need to use more.
Well most users tend to overuse the dry shampoo which can cause clogging the hair follicles and disrupt the balance of a healthy scalp. In addition, this may wear off the surface of the hair strand, causing hair breakage.
In order to keep your hair healthy, stick to dthis type of product just a couple days a week, and never apply more than you can brush out easily.
