Keratin Products: Do They Really Work?
Many beauty products on the market claim to improve the health of our skin, nails, and hair by incorporating keratin into their formulas. From shampoos and conditioners to face masks, lotions, nail treatments, oils, and even hair straighteners, keratin seems to be everywhere. However, it is important to note that there is a lack of scientific evidence supporting the effectiveness of these treatments.
One common misconception is that skin cells can absorb keratin from these products and use it to strengthen the keratin already present in our bodies. In reality, the keratin filaments found in our skin, hair, and nails are already fully formed. These cells are no longer alive, so they cannot grow or enhance these filaments. Therefore, applying keratin-based products topically may not yield the desired results.
Furthermore, it is worth mentioning that keratin hair straighteners, in particular, may not be as beneficial as they claim to be. These straighteners work by breaking the sulfide bonds between keratin filaments, effectively relaxing curls. However, this process can be harmful and damaging to the hair, as it alters its natural structure.
In conclusion, while keratin products may seem enticing and promising, it is important to approach them with caution. The scientific community has yet to establish their effectiveness, and in some cases, they may even have adverse effects. It is always advisable to consult with a professional before incorporating any new products into your beauty routine.
Disorders
Various health problems and disorders can arise from genetic mutations affecting the production or function of keratin. These disorders commonly manifest as skin lesions or mouth ulcers and can also impact internal organs. Keloid disease, characterized by excessive scar tissue growth, is thought to involve keratin, although the exact genes involved have not been identified. Moreover, two specific mutations related to keratin are known to increase the risk of inflammatory bowel disease and liver disorders. Ongoing research continues to explore genetic disorders associated with keratin.
