Choose Best Hair Spray
Hair spray is traditionally a liquid that is aerosolized for application to the hair as a fine droplet film to increase the ability of the hair to stay in place. Hair sprays are generally used on dry hair, to hold and fix a style.
A hair spray is a solution of a polymer which are composed of
dimethylaminoethyl methacrylate (DMAEMA), vinyl acetate (VA), and
polyvinylpyrrolidone (PVP). Here enters the art of the cosmetic chemist
to balance the three substances in such a way as to achieve excellent
hair style hold, minimize the loss of hold with perspiration and
humidity, while allowing shampoo removal to prevent hair spray film
buildup. The balance of polymers leads to high hold and regular hold
formulations. New polymer technology has led to the concept of the
flexible hair spray, which is my haircare recommendation in women with
thinning hair (Pantene Flexible Hair Spray). The flexible hair spray
produces smaller, more numerous welds that allow the hair to bounce
with movement. This creates a more natural appearance.
The hair spray solution in the canister reaches the hair in the form of
a fog of tiny droplets. When these strike the hair they join up,
coating the hair thinly with the polymer. The spray dries very quickly,
since the liquid evaporates almost at the instant it touches the hair.
As it dries the polymer forms light welds or bonds between the strands
of hair. It is these bonds that hold the newly created style in place.
Different types of hair spray are sold, for use on different types of
hair. They differ in the formulation of the holding polymer used, and
also in the way the spray is produced. Polymer sprayed on the hair in
the form of large droplets gives more hold; it takes longer to dry,
however, which leaves the hair feeling sticky for a while. It may also
seem stiffer and rougher when it is dry. Smaller droplets give better
feel, but a less firm hold. It is important to choose the right balance
between hold and feel.
The more heavily the spray is applied, the stronger is the hold. But
there is a definite trade-off: the build-up of polymer on the hair both
looks and feels unpleasant. Some sprays feel sticky after even a fairly
light application. A good spray will give both good 'hold' and good
'feel' without heavy or repeated application, and will be completely
removed by shampooing.
Many women who are experiencing hair thinning like to use high hold
hair sprays that produce a firm hold. The hair spray maintains the
hairstyle by creating welds or bonds between the adjacent hair shafts.
These firm welds are broken with combing of the hair; however, breaking
the welds may also fracture the hair shaft. Many times the welds are so
strong that the hair appears stiff and motionless. Also, the broken
welds result in tiny hair spray fragments that remain on the hair
shaft, making the hair appear dull and feel coarse.
