Switch your shampoo and conditioner
Look for shampoo and conditioner formulated with hair-supporting ingredients like protein, antioxidants, and moisturizing oils to help restore health and strength. Avoid products that contain harsh sulfates, surfactants, or salts that can strip the hair.
There are a lot of products out there — conditioners, serums, shampoos — that promise to heal and restore dry, damaged hair. Sadly, there's really no way to heal damaged hair. Hair is not a living tissue with regenerative abilities, so it can't heal.
A variety of factors may cause 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.
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.
Thyroid Hormone
In hypothyroidism, hair tends to be dry, brittle, dull, and diffusely thinned out – even eyebrow hair can fall out [9]!
Brittle hair could be the result of a number of things, right from constant heat styling, to medical conditions, such as malnutrition, hypothyroidism and a biotin deficiency. This includes using a blow dryer, flat iron, curling rod, and other similar devices.
If your hair feels like straw, it's more than likely because it lacks moisture. A great place to start when it comes to solving dry locks is your haircare regime. Switch things up with different products and be sure to introduce a nourishing treatment mask.
Fried hair can be caused by excessive use of chemicals, coloring, and heating styling products and tools, environmental conditions, and swimming with dry hair. But there are remedies to treat and repair fried hair, such as moisturizing hair masks and using leave-in conditioners.
You can use hair oil, smoothing serum as well as a blow-dry spray. This combination is used by most hairdressers in order to style your hair.
People with very dry hair do not need to wash their hair daily, or even every other day. Instead, washing the hair less often will help preserve the natural oils in the scalp and keep hair well moisturized. Washing their hair weekly or even every other week might be enough for people with very dry hair.
To add moisture to dry hair, we recommend weekly treatments with the Nº. 8 mask for intense moisture, along with adding shine, smoothness, and body.
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.
If you have low porosity hair, it means the structure of your hair doesn't easily allow moisture to be absorbed into your hair shaft. This can make it harder for water to saturate your hair when it's washed. Because this type of hair tends to repel moisture, it can also be more challenging to process and style.
Typically dry hair appears flat and dull, think no shine. Dry hair is also usually more difficult to manage and when you touch it, it has a noticeably brittle texture i.e. knots and tangles, etc. If your hair isn't maintaining a blow-dry this can also be a sign that your hair is lacking hydration levels.
Tangling, knotting, frizz, dullness, breakage: these are all signs of very dehydrated hair. The good news? There are easy ways to treat and prevent not just the annoying symptoms of dryness, but the dry, dehydrated hair itself.
Improper Conditioning
Moisture is the key to having bouncy and shiny hair. That's why your hair becomes dry and brittle when it's deprived of moisture. Skipping conditioning sessions or using a deep conditioner that doesn't suit your hair type will leave your hair dry and feeling like straw.
Hypothyroidism can cause dry hair. With this condition, your thyroid produces too little of the hormones your body needs. Besides dry hair, the condition also causes fatigue, depression, memory loss, weight gain, and other symptoms.
