Signs of keratin deficiency in hair include dryness, brittleness, breakage, lack of shine, frizziness, thinning, split ends, tangled hair, and poor elasticity; essentially, hair becomes weak, dull, rough, and prone to damage, losing its strength and smooth texture because it lacks the essential protein that forms its structure.
Keratin Deficiency
The Bottom Line. Although there are no confirmed cases of harm, the lack of conclusive research and the potential for chemical exposure make keratin treatments best avoided during pregnancy and breastfeeding. Waiting until after this period ensures both your safety and your baby's well-being.
Hair straightening products like the Brazilian Keratin Treatment (BKT) contain high concentrations of formaldehyde, and its use is associated with adverse effects. In 2016, seven cases of eczema-like psoriasiform skin reaction secondary to BKT were described for the first time.
Types of eczema that affect the scalp
In people with lighter skin tones, the skin appears scaly and red. In people of colour, affected areas may be scaly and lighter in colour than the surrounding skin and may have no redness. There is often dandruff as well, which can vary in severity.
The "3-minute rule" for eczema is a key skincare guideline: apply moisturizer to damp skin within three minutes of getting out of a bath or shower to lock in moisture, strengthen the skin barrier, and prevent dryness and itching. This practice, recommended by dermatologists, involves gently patting the skin dry, leaving it slightly damp, and immediately applying a thick cream or ointment to seal in hydration, reducing eczema flare-ups and soothing the skin.
Similarly, experts point to a “three-month rule” for preconception, which is the idea that you and your male partner or sperm donor should take three months before even trying to conceive to set the foundation for a healthy pregnancy.
Who Should Avoid It?
It is found in high concentrations in animal products such as meat, poultry, fish, eggs, and dairy products. Vegetables also contain small amounts of keratin. Keratin-rich foods are important for maintaining healthy hair, skin, and nails because they provide the body with the protein it needs to produce keratin.
Vitamin H is known to stimulate hair growth. Studies have shown that biotin deficiency can lead to hair loss. While biotin can be used to treat hair loss, the best results occur in individuals who are biotin deficient. However, biotin deficiency is quite rare as it is found in many food sources.
Biotin helps your hair grow from the inside out by nourishing the follicles and promoting keratin production. Keratin repairs the hair from the outside, resulting in less frizz and stronger hair if your hair is damaged, making it feel smoother and look healthier. Both are important, but they do different things.
What are the symptoms of low protein in blood?
Androgenic alopecia (hormonal alopecia) is the most common cause of hair loss in women. It is generally described as female-pattern hair loss. It usually occurs after menopause due to an excess of androgens (“male hormones”), such as testosterone and dihydrotestosterone (DHT), also known as the balding hormone.
Signs Your Hair Needs Protein:
Cezanne is one of our top choices for formaldehyde-free smoothing. This treatment uses sericin, a natural protein derived from silk, to smooth and strengthen the hair without harmful chemicals. It lasts up to five months, reduces frizz, and enhances shine—all while keeping the hair's natural volume and movement intact.
Does keratin make thin hair look thicker? It can make it appear fuller and smoother because of the coating effect, but it doesn't increase actual hair growth.
Many people with curly and coarse hair types use keratin because it makes their hair feel smoother and, in turn, more manageable. By nature, curly hair is more porous and, therefore, more prone to damage. By treating it with keratin-based products, it can become more resilient, healthier, and shinier.
The risk of miscarriage: You may not feel comfortable talking about pregnancy losses, which could make follow-up conversations harder if you share early on in your pregnancy. “The risk of miscarriage is the highest in the first trimester, which is why some people wait to announce their pregnancy,” Weiler said.
The "worst week" of pregnancy varies, but many women find the first trimester, particularly weeks 8-10, to be the most challenging due to intense morning sickness (nausea/vomiting peaking with hormone surges), extreme fatigue, and heightened emotional changes, though some experience severe symptoms like hyperemesis gravidarum (HG) requiring medical attention, while others face discomforts in later pregnancy.
The third month of pregnancy is when an embryo becomes a fetus. It's a period of rapid growth and development. The fetus develops distinct facial features, limbs, organs, bones and muscles. By the end of the 12th week, the fetus has an assigned sex, but it won't be visible on ultrasound for several more weeks.
People with severe eczema may be low in vitamin D, some research shows. In studies on a very small number of people, eczema symptoms got better a month after they started taking vitamin D every day. The adult dose is 600 international units (IUs) a day. Infants and children up to the age of 12 can have 400 IUs.
But a major study now says eczema patients can choose to wash up either daily or just one to two times per week without any fear of their symptoms getting worse.
If you have eczema, your skin probably has a higher than normal pH. A natural skin pH level under 5.0 is considered healthy. Apple cider vinegar is a mild acid, so applying it to your skin may restore the natural pH level, relieving eczema symptoms. Use mild soaps or body cleansers.
