Signs of keratin deficiency in hair include brittleness, excessive breakage, split ends, dullness, frizz, thinning, and difficulty holding color, as the hair lacks the essential protein for strength, elasticity, and smoothness. Your hair may feel dry, rough, porous, and prone to damage from heat or environmental factors, indicating a depleted keratin stock.
Keratin Deficiency
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.
While keratin treatments are popular for achieving smooth, frizz-free hair, they're generally not recommended during pregnancy or breastfeeding.
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?
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.
However, it's crucial to keep in mind that keratin treatments do involve chemicals, and overuse can potentially harm your hair. Some people might reveal inside results, such as itching or inflammation at the scalp.
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.
Many foods contain some biotin. Foods that contain the most biotin include organ meats, eggs, fish, meat, seeds, nuts, and certain vegetables (such as sweet potatoes) [2,12].
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.
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.
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.
Skin barrier and inflammatory changes in atopic patients may explain increased itch before bedtime.
Signs and symptoms of scalp psoriasis
Reddish patches on the scalp, sometimes thick and inflamed. Dandruff-like flaking and silvery-white scale that looks like dandruff. Dry scalp that may crack and bleed. Mild to intense itching.
Generally, washing your hair every other day or even less frequently is a good starting point. However, the ideal frequency will depend on your hair type and the severity of your eczema. If you have oily skin hair or experience frequent flare-ups, you might need to wash more often.
Eczema Friendly Shampoos
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.
10 Foods Rich in Keratin & Biotin that Improve Hair Growth
Using Sulfate Shampoos: Sulfates strip away the keratin layer, making the treatment fade much faster. Always use sulfate-free, gentle shampoos and conditioners. Skipping Heat Protection: While keratin smooths and strengthens, excessive unprotected heat from styling tools can cause dryness and breakage.
