Biotin. Biotin is an essential B vitamin (meaning we need to consume it daily) that's known to be important in hair and nail growth. "When patients have a biotin deficiency, they suffer from thinning, dry hair, and dry skin," says Zeichner.
Vitamin A for dry hair and skin
People struggling with chronically dry hair or skin should prioritize increasing the consumption of vitamin A. The vitamin is considered especially vital for all cells in the body and is linked with helping the skin glands create sebum.
You can help replenish this loss by using a deep moisturizing shampoo and conditioner, along with a leave-in moisturizing spray. Reducing the amount of times you wash your hair in a given week can also help prevent excess dryness.
Brittle hair and nails
One of them is a lack of biotin. Biotin, also known as vitamin B7, helps the body convert food into energy. A deficiency in biotin is very rare, but when it occurs, brittle, thinning, or splitting hair and nails are some of the most noticeable symptoms.
So, for healthy hair, eat biotin-rich foods such as eggs, liver, milk, soy, hazelnuts and yeast. Generally, a varied and well-balanced diet will bring you all the essential nutrients your hair needs to be healthy and strong.
Our skin glands produce less sebum making our tresses feel perpetually dry. Having low hair porosity or even high hair porosity and using the wrong products can also contribute to having dry hair, even when using a conditioner. Low porosity hair is hard to hydrate while high porosity hair loses moisture easily.
Diet can certainly have an effect on hair health. If you have certain nutritional deficiencies, you can have dry and stringy hair and even experience some hair loss. Hair derives its nutrients from blood flow under the scalp where hair roots are housed within the follicle, according to TS.
Straw-like hair is often the result of common hair care oversights, such as these: using drying and styling tools (dryers, curling irons, electric rollers, flat irons) at too high a heat setting. using heat-based drying and styling tools too frequently. shampooing too often.
using heat-based drying and styling tools too frequently. shampooing too often. using a shampoo with harsh ingredients, such as sulfates, that are drying for your type of hair. not using a conditioner often enough or one that's designed for your type of hair.
Thyroid Hormone
In hypothyroidism, hair tends to be dry, brittle, dull, and diffusely thinned out – even eyebrow hair can fall out [9]!
Also, in response to the loss of estrogen and progesterone the body produces more androgens. Androgens shrink hair follicles which make hair grow thinner. Declining estrogen is the cause of the dryness.
“A reduction in estrogen results in reduced sebum (oil) production, which normally lubricates the scalp. The result is dry skin and a flaky scalp,” says Kunin. And, since that hydrating scalp oil isn't there to work itself down your strands, hair is also drier, as well as duller, more brittle, and breakage-prone.
If your hair is too dry this usually is caused by a deficiency of fat soluble vitamins, especially vitamin A (retinol) which helps regulate the sebaceous gland. Vitamin D and vitamin E are also involved.
Can Vitamin D Deficiency Cause Hair Loss? Vitamin D is metabolized in the skin by keratinocytes. These are skin cells that process keratin, a protein in hair, nails, and skin. When the body doesn't have enough vitamin D, keratinocytes in hair follicles have trouble regulating hair growth and shedding.
A zinc deficiency can cause diffuse hair shedding and breakage — as well as other symptoms, such as stunted growth and poor immune system function. It is preferable to obtain zinc through your diet, rather than supplements.
Hair health
Drinking enough water keeps your hair hydrated. As such, one can truly avoid hair loss, hair fall, dry hair, brittle hair and itchiness. Your scalp remains hydrated and healthy by having the correct amount of water in the diet.
Using products that are designed to nourish the scalp and hair can definitely speed up this process, but on average you'd be looking at six months to a year to fully see a difference in your hair's condition.
All hair needs both protein and moisture to stay healthy and strong. In fact, protein and moisture can't work well without the other. You need a strong protein structure in order for water molecules to bind with your strands and to keep the water locked inside.
