HAIR
AMINO ACIDS, WHY YOU NEED THEM
What are Amino Acids
Amino acids are very small molecules, they are not "proteins" by themselves, they are the constituents of the proteins formed.
To have a protein, you put these Amino Acids together.
Where they are (hair)
In hair, there are many amino acids (at least about 20).
The cuticle of the hair - it is an outer covering with several layers of "scales", contains more amino acids than in the inner parts of the hair fiber.
How amino acids are lost
The content of amino acids when exposed to chemicals or heat sources, there is a degradation of hair proteins. Therefore, using serum will be more efficient. You have a recipe below
Do amino acids remain in my hair?
You may have heard that amino acids are simply eliminated when they are included in a shampoo or conditioner. This is not entirely true. If you apply amino.
Now, if amino acids are present in a formula (like a conditioner), the amino acids stick more difficult because they interact with the other ingredients.
Which one should you look for?
Silk Amino Acids or Silk Protein
Contains: alanine, glycine, and serine.
Function: improves moisture, elastic capillary strength and protection against aggression
Hydrolyzed Wheat Protein contains:
cysteine, glutamic acid
Function: improves hair moisture, adds volume, reduces porosity
Improves smoothness.
Hydrolyzed Oat Protein and derivatives contains:
Glutamic acid, aspartic acid, alanine, proline
Function: Decreases the static electricity charge on hair strands, protects natural or dyed color against UV rays.
Hydrolyzed Soy Protein and derivatives: contains: phenylalanine, tyrosine, leucine
Function: ability to keep the cuticle smooth, repair and strengthen the hair, maintenance of curly hair structure
Hydrolyzed Protein Keratin contains:
Cysteine, tyrosine, glutamic acid
Function: restores elasticity and strength
Restructuring power of the hair fiber.
NOTE:
If you are allergic to any of these ingredients (such as wheat) or have an intolerance that causes severe physical symptoms, you may also need to avoid the hydrolyzed versions of the proteins.
WHERE TO BUY
Shops or Websites for cosmetic actives
COST $ : A 30ML bottle that lasts a long time, because you will use only drops, costs around twenty-eight reais (BRA)
HOW TO USE
Make a serum with water and protein in the percentages indicated on the label and apply to clean hair.
Let it act for 20 minutes and add a layer of conditioner or nourishing cream, wait another 20 minutes and rinse.
Finish as usual
