1. Do hair keratin treatments work for your hair?

2. Hair Hair is a protein made up of keratin
as hair cells grow, they fill up with the fibrous protein of keratin
cells lose nucleus and therefore die as they travel up the hair follicle
91% of hair is protein made up of long chains of amino acids
Polypeptide chains intertwined to create helix shape
Keratin found in hair is water resilient

3. Keratin infused shampoo
Smoothing Therapy Keratin Color Care Shampoo by Keratin Complex
Main ingredients include water, hydrolyzed keratin, hydrolyzed wheat protein, and hydrolyzed soy protein
Hydrolyzed keratin/protein in keratin shampoo is broken down into its component amino acids
Hydrolyzed wheat targets cortex to strengthen it, hydrolyzed soy protein targets hair fiber to add shine and smooth strand (salon treatments)
Some treatments contain formaldehyde: known to be a carcinogen; high heat must be applied in order to seal product (breaks amino acid bonds in hair)

4. Statistics/Reviews of treatment
Reviews state keratin does not actually smooth your hair
The ammonium thioglycolate and sodium peroxide found in shampoo that straightens hair is said to leave hair shaft feeling brittle
Shampoo does not work immediately, usually just coats shaft to seal treatment (at home shampoos)

5. Shampooing process- Does it work?
For a brief period of time – yes
Your hair needs not only keratin infused shampoo but shampoo that includes hair healthy ingredients such as shea butter or jojoba oil
The effectiveness of the shampoo depends on the quality of the shampoo brand

6. Positive/Negative affects of keratin
Salon treatment temporarily straightens and smoothes hair; damages hair in process
Keratin does add needed extra protein to hair; but also adding too much keratin over time leads to hair loss
Horror story of hair loss due to keratin treatment; puts physical stress and damage on hair
FDA is doing research on long term effects of “Brazilian blowouts” (salon keratin treatment)
