I wanna apply keratine for he first time. Is it healthy? My hair is a bit thin. Will it affect my hair's health and quality? Are there specific keratine types healthier than others?

Keratin is a protein found naturally in the human body that makes up physical structures such as the hair and nails. When these basic structures become weakened and keratin is lost, it is possible to add keratin through cosmetic processes to fill in gaps in the original keratin fibers, providing better strength. Most commonly, people use keratin as a hair straightening treatment. The possible keratin side effects include hair loss, allergic reactions, itching, rashes, irritation of the eyes, lungs, throat, mouth and nose, hair dryness, and cancer. These side effects are not from the keratin itself, but from the processing tools and additives included with the keratin products that help them work.
Some people who use keratin products find that, after a treatment, hair is extremely dry and brittle. In some cases, this leads to breakage and thinning of the hair. This happens because cosmetologists use heat-based styling tools such as flat irons to coax the hair straight. The heat saps the moisture from the strands and causes a loss of elasticity. The problem worsens as an individual continues to style the hair with heat-based tools, unless she is vigilant about using conditioning and moisturizing treatments.
Almost all of the other keratin side effects are due to the formaldehyde the products include. Formaldehyde helps hold the keratin molecules together, which is largely what makes the product effective. This chemical is a known carcinogen. Problems such as irritation of the throat and lungs come from inhaling the formaldehyde during processing. Experts recommend that keratin products have no more than 0.02 to 0.2 percent formaldehyde for this reason, but this is problematic because the treatment is not as effective with anything less than 2 percent, with many manufacturers making products with percentages as high as 10 percent.
