Research shows that changes in your hair's look, texture, or thickness can be signs of underlying health conditions. Here's how you can tell whether your hair changes are due to a health problem, genetics, stress, or a nutritional deficiency.
Your hormones are out of balance.
A sudden increase in hair growth or loss in women is often caused by an imbalance of male hormones, which are naturally present in both men and women in differing amounts. If you get an increase in testosterone, for example, excess hair can be the result.
Vibrant, healthy hair means that your body is producing enough vitamins and nutrients that ensure the body is operating at its peak condition. Unhealthy, dry and frizzy hair may be a sign that you may need to change your diet or hair care routine in order to promote your overall health and well-being.
Unhealthy hair usually has a rough texture, lack of shininess and luster, have split ends, lack of moisture and elasticity even after treatment and easily broken. Damaged hair will also get tangled up and result in knots due to hair dryness.
A healthy scalp leads to healthy hair, so it's important to pay attention to your scalp. If you notice any itching, redness, flakiness, irritation, pain, or excessive hair loss and these symptoms bother you, see a dermatologist.
“A healthy scalp is free of flakes, pimples and dry patches—the scalp will look clean, smooth and moisturized with no breaks or cuts in the surface,” says Dr. Kari Williams, a board-certified trichologist, licensed cosmetologist and member of DevaCurl's Expert Curl Council.
Rossi generally tells his patients they should wash their hair once or twice per week. But if you've had chemical treatments that can make your hair drier — such as bleach, perms or relaxers — you might want to wash it less than once weekly to avoid breaking or brittle hair or split ends, he said.
"Hair that is low porosity will float. Hair that is 'normal' porosity will float and then begin to sink slowly. Hair that is high porosity will sink immediately."
By sliding a strand, or a few, between your thumb and forefinger, you might be able to feel for the health of your hair. A smooth, easy slide, likely means your hair is healthy, while a rough and bumpy feeling means you likely have some damage.
Changes in your hair could indicate nutrition and health issues. A dry scalp or hair could mean you aren't getting enough healthy fats in your diet. Likewise, thinning hair could mean your diet lacks protein.
Biotin. Biotin, also known as vitamin B7, is a complex B vitamin that is often touted for having hair growth benefits. And some of that hype may actually be worth it. Biotin has functions in “creating red blood cells, which carry oxygen and nutrients to the scalp and hair follicles,” says Dr. Green.
Getting gorgeous hair has so much to do with its roots because healthy hair starts at the scalp. Your scalp is the location of your follicle. It is also the place where your blood vessels feed nutrients and oxygen to the follicle.
A hairy chest signals higher intelligence in a man, somewhat tongue-in-cheek research finds. Dr Aikarakudy Alias, a psychiatrist, has found that hairy chests are more frequent among men who are highly educated, such as doctors.
It's believed that when our hairs gets longer, our head gets Vitamin D, phosphorus and calcium naturally. They in due course, enter into our body via two of the tubes which're at the brain's top part. This alteration alters our memory more strong and efficient.
Thicker strands of hair are more likely to have a defect, making them more prone to breakage, the researchers believe. Lustrous, thick hair may be desirable but it is not necessarily the strongest. Scientists said thin hair tends to be stronger than thicker locks, after looking at the way they break.
It's smooth and soft to the touch.
Depending on how your hair feels to the touch, you might be able to quickly and easily determine if your hair is healthy. "If your hair is properly moisturized, your hair will be smooth and soft when you run your fingers through," Fink said.
Wet hair is far weaker than dry hair, being more susceptible to breakage and damage from just about anything – heat and pulling on the hair strands are more likely to damage wet hair than dry. Hair is made up largely of a number of proteins called keratins.
Normal porosity hair allows moisture to pass into the cortex as needed, but resists permitting too much water to penetrate. Repeated works by various research groups have found that healthy hair of average porosity can absorb water up to a maximum of 31.1% by weight.
Harsh shampoo, hair treatments, styling products, and excessive brushing contribute the most to poor hair health. However, other culprits include: overconsumption of alcohol. low-calorie and crash diets.
Diagnosing Weak Hair
Weak hair can be defined as limp, droopy, thin or falling out. Split ends, extreme dryness or excessive oiliness can all be signs of weak hair.
Fortunately, in the vast majority of cases, you can eventually grow the damaged hair out as long as the follicle itself has been preserved. The most common causes of damage are below. Damaged hair can still grow eventually, but routine damage can result in negative consequences for your hair.
Most people should wash their sheets once per week. If you don't sleep on your mattress every day, you may be able to stretch this to once every two weeks or so. Some people should wash their sheets even more often than once a week.
Going a long time without washing your hair can cause a buildup of a yeast-like fungus called Malassezia on your scalp. Over time, this leads to a layer of dead skin cells that shed from your head in the form of oily, yellow-ish dandruff flakes. Dandruff can also make your scalp red, scaly, and itchy.
Many doctors say a daily shower is fine for most people. (More than that could start to cause skin problems.) But for many people, two to three times a week is enough and may be even better to maintain good health. It depends in part on your lifestyle.
