1. Common causes of dry, frizzy hair

Dry hair is caused by the scalp not producing enough oil to moisturize the hair or the hair losing moisture. Hair is not naturally self-lubricating. The amount of oil secreted from the roots of the hair is to moisturize the hair and help them look shiny.
Sometimes, the hair does not produce enough oil causing the hair to become dry and frizzy. The hair roots compensate by producing more oil, which manifests as shiny hair. Hair produces less oil in older people due to the aging process. However, because the hair roots are located under the skin, dry hair is often accompanied by a dry scalp. When dry, the scalp flakes and causes dandruff.
The moisture of the hair can also be lost causing the hair to dry out. Every healthy hair has a protective layer called the cuticle. The cuticle covers the outside, which is responsible for protecting the hair from the harmful effects of the sun and heat. A healthy cuticle consists of many layers that line up close together and retain moisture inside.

2. What to do with dry hair?

Some simple solutions to help protect hair from drying out such as:
Wash your hair less. Hair should be washed from dirt once or twice a week instead of daily as many people do. In addition, when you no longer wash your hair as often, the frequency of hair drying and styling also decreases. Use mild shampoos that are specifically made for frizzy hair because they will have less drying chemicals. Use alcohol-free hair chemicals. After shampooing, use a moisturizing conditioner. Moisturizing conditioner will help protect the cuticle and retain the hair's natural oils. Massage your scalp with coconut or jojoba oil. After trying all of the above methods, if the condition of dry hair does not improve, you should consult a hair stylist for advice on other intensive treatment measures. In addition, if dry, frizzy hair appears along with other symptoms such as fatigue, poor cold tolerance, weakness in the limbs or hair loss, the patient should see a doctor to rule out other possible systemic diseases. .
