How long does it take for alopecia areata to grow hair

Alopecia areata is a relatively common hair loss disease. People also call this type of alopecia areata "alopecia areata". Sometimes patients will experience local hair loss at night without realizing it. There are many causes of alopecia areata, including disease and psychological reasons. If you have alopecia areata, you should receive good treatment in time. There are drug treatments, such as minoxidil, 5% minoxidil cream, etc. Let us learn about this aspect.

How long does it take for hair to grow after alopecia areata

Generally, after treatment, alopecia areata will heal in 3 to 4 months and hair will start to grow. However, those with higher difficulty may not be cured for several years. The question of how long it will take to cure alopecia areata should be analyzed specifically for different treatments. Usually, different methods of treating alopecia areata will result in a big difference in how long it will take to cure, so it cannot be determined. Alopecia areata is a disease that is prone to recurrence, and the specific situation of each patient will be different.

Some patients with alopecia areata have smaller bald spots, with only 1-2 patches, which stop expanding within a few weeks. The hair around them grows firmly without any symptoms of loose hair. This is a sign of improvement. Soon, fine, light-colored vellus hair will appear on the smooth bald spot, gradually turning darker, thicker, and denser, and the hair will return to normal. Alopecia areata often recurs after recovery. Some patients relapse after a few months, while others relapse after a few years.

Some patients relapse only once, while others relapse multiple times. There is no regular recurrence of alopecia areata, and some patients may have a relapse after 5 years. All types of alopecia areata may recur, with different intervals between recurrences, which brings a great mental burden to patients. Patients with alopecia areata must avoid being impatient for quick results during treatment. The more anxious they are, the longer the treatment cycle will tend to be. Adjusting your mindset and paying attention to rest and diet are good ways to assist in treatment. If you want to choose folk remedies to treat alopecia areata, you must first obtain the consent of your doctor to avoid being deceived.

Treatment of alopecia areata

Most common alopecia areata tend to heal naturally, but a few cases recur, making them difficult to treat. But there are many treatments that can be combined to treat hair loss. 1. Topical medications (1) Minoxidil 5% minoxidil cream or solution, applied once or twice a day, may be related to its vasodilatory effect. (2) Anthralin 0.5% to 1% anthralin ointment or cream is a primary irritant. Apply externally 1 to several times daily, until mild dermatitis occurs on the local skin. (3) The contact sensitizer diphenylcyclopropene ketone (DCP) is the most commonly used. (4) Topical or intraperitoneal glucocorticoids. Topical application of 0.05% dexamethasone and 50% dimethyl sulfoxide solution often has better therapeutic effects than creams. 2. Oral medication (1) The glucocorticoid prednisone is taken orally. The dosage is gradually reduced after a few weeks and then maintained at a low dose for 6 months. Glucocorticoids are effective, but have significant side effects and are prone to relapse after discontinuation of the drug, so they are not used as a routine treatment. However, it can be tried for acute alopecia areata to prevent it from developing into total alopecia or universalis. (2) The course of cyclosporine treatment is 6 to 12 months. It is effective in some cases, but the drug should be discontinued if there is no effect after 4 months. (3) Thymopentin is injected intramuscularly for 3 weeks. (4) Take niacin, a vasodilator, orally. 3. Local injection method: Local injection of glucocorticoids is suitable for hair loss in a smaller area or important cosmetic areas (such as eyebrows) in patients with alopecia universalis. The injection can be directly into the hair loss area or into its surrounding area in order to control the further expansion of the hair loss area. Care should be taken to avoid possible local skin atrophy and depression. 4. Nerve blockade therapy: The greater occipital nerve is blocked. After the nerve is blocked, the skin temperature in the area it innervates rises, which is beneficial to hair regeneration.
