Keratin for hair: salmon, eggs, and onions are great sources of keratin for hair growth and health.
What is Keratin: As stated by Healthline’s 2018 article on keratin, “keratin is a type of protein that makes up your hair, skin, and nails.” Keratin can also be found in our internal organs and glands. It is a protective protein and therefore less prone to scratching or tearing than other types of cells. Keratin has several health benefits, in particular to the hair and the nails.
Keratin can help all hair types from curly, wavy, straight, and more in many ways:
No matter your questions or your specific hair type, keratin is an essential component of hair health in general. Even if you have healthy, beautiful, voluminous hair, keratin is still critical for combating the degeneration of hair that comes with age.
Using keratin for your hair have long-lasting beauty and health benefits that you’ll thank yourself later for. Yet, it is also important to note that not all keratin supplements and topicals are created equal.
Keratin is also known to aid nail growth and nail strength.
In a 2021 study published in Trichology and Cosmetology OpenJournal, researchers tested the effectiveness of keratin hydrolysate in hair and nail growth on adult females. Researchers concluded that a “natural extensively hydrolyzed keratin” has improved hair and nails condition after a 3 month intake period.
Specifically, researchers in this study reported that “nails improved in condition after 45 and 90 days of treatment. After 90 days of use, 60% of the subjects showed an improvement in nails condition. This conclusion was demonstrated by an increase in nail growth by 0.14 mm / 14 days to show how successful keratin can be in improving nail health.
Keratin synergizes with other natural ingredients to strengthen hair at a cellular level by smoothening down outer cells that make up hair strands. As new keratin proteins reach the hair, these new proteins smoothen and fortify pre-existing keratin proteins found along or within damaged hair. This process fills and repairs gaps found along the rough or damaged exterior of hair strands, which results in a fuller and smoother hair strand that looks glossy and healthy. A person suffering from keratin-poor hair can expect hair breakage, low hair volume, and an inability to sustain a good hair length.
In a 2018 study, researchers concluded that “K31, a type I acidic keratin, is a major protein of the human hair keratin complex and is essential in maintaining hair tensile strength.”
More so, researchers found that keratin is a significant protein lost in damaged hair – and that by applying keratin K31 or hydrolyzed keratin peptides isolated from wool or chicken feathers, a cohesive film can be formed to fill the gaps produced in damaged hair. Researchers also found that when applied to hair, keratin increases the diameter of the individual hair strand by up to 49%.
Furthermore, other findings report that keratin applied to hair increased mechanical strength by up to 2 fold after a single treatment.
Keratin’s effectiveness in improving hair and nail health is also discussed in this Journal of Biomaterials Applications study published in 2017. Researchers in this study concluded that “keratin extract topically applied” can significantly increase the number, shaft of hair follicles in the keratin extract-treated group in contrast to the control group, which was considered an indication of anagen phase induction.”
More so, a different study published in Research Square in 2020 further supports this claim when researchers stated that “keratin exposure appears to be critical for dermal papilla cell condensation and hair germ formation – as immunodepletion and silencing keratin prevent dermal papilla cell condensation and hair germ formation.
Furthermore, silencing keratin in mice “resulted in a marked impression of anagen follicle formation and hair growth.” Finally, another study that supports keratin’s essential role in the development of new hair can be found in this 2006 study which states how keratin-null mice developed alopecia (hair loss or inability to grow hair) in the first-week post-birth, “correlating with hair shift fragility and untimely apoptosis in the hair bulb.”
All of these findings support how keratin is a significant component of hair and an important component in hair growth and production.
These research and findings suggest that keratin application can be recommended as a possible solution for treating alopecia or hair loss or as a great way to maintain hair health and beauty.
Keratin is popularly used in three different ways for hair. These include:
When you research the health benefits of keratin on the internet, several sources focus on “keratin treatment.” As stated by Healthline, keratin treatment, also known as a Keratin chemical hair treatment or a Brazilian Blowout, is a chemically-based hair treatment generally done in hair salons, often with potentially toxic chemicals and mainly used to make hair look straighter temporarily.
The keratin treatment process involves a blow dry of the hair and then applying the treatment to dry hair. Then, a flat iron is used to seal the treatment within the hair.
There are many positive reasons as to why some people would want a keratin treatment.
Although keratin itself won’t damage your hair, most keratin treatments use formaldehyde, a potentially toxic chemical, as part of the treatment to straighten the hair in preparation for keratin.
As stated by the CDC, formaldehyde is an eye, skin, and respiratory tract irritant and has many severe health risks and effects when inhaled or ingested. Children may be more susceptible than adults to the respiratory effects of formaldehyde, which includes:
The systemic effects of formaldehyde are due primarily to its metabolic conversion to formate and may include metabolic acidosis, circulatory shock, respiratory insufficiency, and acute renal failure. More so, formaldehyde is a potent sensitizer and a probable human carcinogen.
Workers and professionals who administer keratin treatments have reported damage to their bodies due to the toxicity of these chemicals used before applying keratin.
Although there are several hair benefits to keratin treatment, experts recommend a more natural approach because these methods can be done without the dangers associated with a keratin treatment.
There are several topical products available on the market infused with keratin. To determine the accuracy of these products’ claims, it is best to check product labels to determine keratin type and dosage, precautions, and warnings.
Keratin topicals, such as gels, creams, lotions, and ointments, can be used as hair masks to treat the hair in a much safer manner than Brazilian blowouts. Keratin-infused shampoos and conditioners can add the benefits of keratin to hair strands to combat hair frizziness and breakage.
For example, if you have brittle, damaged hair, keratin topicals or shampoos, pomade, lotion, or ointment can help replenish and protect your hair’s natural keratin protein – reversing damage and preventing future breakage. As a bonus, keratin applied to the hair via a topical can dramatically improve your hair’s elasticity for a healthier, more youthful bounce.
Generally, you can expect a keratin topical to have approximately the same benefits as a keratin oral supplement. The main difference is that if you choose only to use keratin topical, you may not receive the full holistic, whole-body benefits of ingesting keratin, such as improved skin and nail health in addition to better hair health. On the other hand, with a keratin topical, such as an ointment, lotion, cream, or pomade, you can choose and focus on the targeted area – such as specific balding spots on the scalp for a more targeted approach.
According to the EWG, keratin has an ingredient score of 1-2 which states that keratin has no cancer, developmental and reproductive toxicity, allergies, and immunotoxicity dangers for human consumption or application.
Keratin, under recommended doses, can be taken safely orally via capsule supplement as part of a dietary supplement.
It is important to note that dosage should be considered carefully. Although keratin is a natural protein found in the human body, ingesting too much keratin can still lead to dangerous side effects such as excessive protein buildup. Experts do warn that taking an excessive amount of any protein is not recommended. If you are looking for keratin supplements, it is best to first talk to your doctor to see if this is right for you. It is also important to note that all-natural ingredients harmonize with the body better than non-natural ingredients.
In this 2013 study, researchers found that protein hydrolysates, particularly those with low molecular weight, are known to “provide efficient protection and care to hair.” These researchers reported that the lighter the keratin molecule, the more capable it is of penetrating the cortex of the hair fiber, and the better the molecule serves to promote a surface coating. These processes have “beneficial effects on hair structure, replacing lost keratin, and can also have an antiaging effect.” These researchers concluded that keratin hydrolysates, also known as hydrolyzed keratin, have “increased the hydration of hair fibers,” as well as “sealed cuticles in hair fibers treated,” to present a “significant increase of the brightness and softness of hair.”
Therefore, the quality and source of the keratin are all crucial factors to consider for maximizing its effectiveness in treating hair loss or promoting hair growth.
Whether you choose to use keratin oral supplements or topicals, both methods have been reported to work with similar results for hair growth or improved hair health.
Hydrolyzed keratin, which is a broken-down form of natural keratin better suited for hair growth, is one of the many powerful, all-natural, and plant-based ingredients found in Dr.UGro Gashee Oral Hair Supplements. To help increase the feel and appearance of hair density, thickness, and volume, or to help regrow hair lost or aid hair growth, take 4 capsules a day.
Jovon came in for a consultation because she noticed that her hairline was receding. She noticed bald patches on the back of her head, as well as chunks of hair that fell out in the shower or whenever she combed her hair. Fortunately, after trying hair growth products that did not work, Jovon stumbled on Dr.UGro Gashee Instagram Page.
In 4 months of Gashee all-natural hair growth oral supplements, Jovon was able to grow back her hairline and reports that her hair is now “a lot thicker” and that her hair had stopped “falling off.” More so, as an added benefit, the keratin found in her Gashee oral supplements was also able to strengthen her nails: she reports that her nails grew “a lot faster and longer” while she was under Gashee oral supplements.
