Although dry hair is not uncommon, it can be caused by external or internal factors. Dry hair can result from overusing hair styling tools with high heat, such as a blow dryer, curling iron or flat iron. In addition, some illnesses or medications can cause your hair to become dry. Different types of treatments can help restore moisture to dry hair, depending on the cause.
Identification
Dry hair looks dull, lacks volume and appears lifeless. It breaks easily, may have split ends and looks frizzy. A number of factors can cause dry hair.
Damaged Hair
Your hair may be dry due to harsh hair care products or overuse of heated styling tools. Frequent shampooing can strip the scalp of its natural oils. Sebaceous glands located near the hair follicles constantly secrete oil to hydrate your scalp and hair. If this process fails, your scalp dries out, leading to dry hair.
Environmental Factors
Dry hair may be due to environmental factors such as cold, arid climates. Air conditioning and central heating suck the moisture from air, leading to low levels of humidity. This in turn causes dry scalp, hair and skin. Long or very hot showers also can dry out your hair. The type of water you use to wash your hair can make a difference as well. Some water sources are hard water, which can cause a buildup of minerals such as calcium and magnesium on your scalp, drying out your hair.
Medical Concerns
Dry hair may be a sign of inadequate nutrition, dehydration or illness. Hypoparathyroidism and hypothyroidism, in which the parathyroid and thyroid glands don't produce enough hormones, both cause thin, brittle hair and nails. Both conditions require professional treatment and medication.
Malnutrition and eating disorders result in a severe lack of vital nutrients. When your hair is undernourished, it becomes dry and prone to breakage. These conditions require more than just a well-balanced diet; they also require doctor-supervised care.
Solutions
A healthy diet will benefit your hair as well as your scalp. Dry hair can result from dehydration, so drink plenty of water. Control environmental factors when possible; otherwise, use hair care products that will protect your hair from damage.Try natural or organic shampoos, which are safe but clean effectively. These shampoos are formulated with such ingredients as lavender, jasmine, coconut oil, rosemary or white camellia as well as filtered or deionized water, which is gentler on your hair than the harsh chemicals in many other commercial products. Instead of using shampoo every time, wash your hair with conditioner, which will clean your hair while keeping it moisturized. In addition, hot oil treatments containing herbs such as peppermint, rose, tea tree oil, chamomile or myrrh are good for damaged, dry hair.
Warning
If home treatment and lifestyle changes don't improve your dry hair, contact your doctor. An underlying medical condition could be causing your hair problems.
