Hair Problems and Re
Dry hair is caused by heat, an open cuticle, chemicals applied
to the hair, and poor maintenance.
SOLUTIONS:
-
1) Less or no heat. When blow drying, use a cooler setting and
do not blow dry until the is completely dry.
2) Use acidifiers. Acidifiers close the cuticle down and lock
in moisture. Acidifiers have a pH of 2.5 to 3.5. They have a
lower pH than hair does in an aqueous solution.
3) Color, perms, relaxers, and other chemicals are sometimes
a necessary evil. They rob the hair of humectants. Humectants
attract and retain moisture (water) in the cortical layer of
the hair. Try to use low ammonia -low peroxide color. Do not
leave neutralizer on too long with perms. If possible avoid
relaxers.
4) Treat your hair. Replace lost humectants with essential
fatty acids (lipids), acidify your hair, use low
pH products, use cool water. Replace what was taken out to make
your hair......

Hair Problems and Re
Hair is composed primarily of proteins (88%). These proteins are of
a hard fibrous type known as keratin. Keratin protein is comprised
of what we call "polypeptide chains.” The word, polypeptide, comes
from the Greek word "poly" meaning many and "peptos" meaning digested
or broken down. In essence, if we break down protein, we have individual
amino acids. Many (poly) amino acids joined together form a "polypeptide
chain". Two amino acids are joined together by a "peptide bond", and
the correct number of amino acids placed in their correct order will
form a specific protein; i.e. keratin, insulin, collagen and so on.
The "alpha helix" is the descriptive term given to the polypeptide
chain that forms the keratin protein found in human hair. Its structure
is a coiled coil. The amino acids link together to form the coil and
there are approximately 3.6 amino acids per turn of the helix (coil).
Each amino acid is connected......
