What should I do if my eyebrows don't grow back after being shaved?

Under normal circumstances, eyebrows may stop growing after shaving due to frequent plucking, improper cleansing, malnutrition, folliculitis, hypothyroidism, or other reasons. Treatments such as eyebrow tattooing, eyebrow transplantation, fractional laser therapy, or medication can be used under the guidance of a doctor. It is recommended to visit a reputable hospital and undergo related procedures under medical supervision to ensure effectiveness and safety. Detailed analysis is as follows:

1. Frequent Eyebrow Shaving

The eyebrow growth cycle is relatively long. Excessive shaving may damage hair follicles, leading to difficulty in eyebrow regrowth. It is advised to reduce the frequency of eyebrow removal and avoid over-stimulating the follicles. Alternatively, eyebrow tattooing may be performed under a doctor’s guidance—this involves implanting plant- or metal-based pigments into the superficial skin layers to create a suitable eyebrow shape based on facial features, thereby improving appearance. The typical reference cost for eyebrow tattooing ranges from 800 to 3,000 yuan per session. Improvement is usually seen within 1–2 weeks, although side effects such as allergic reactions or infection may occur.

2. Improper Cleansing

Failure to properly clean the skin after shaving may lead to clogged hair follicles due to oil and dirt buildup, impairing normal eyebrow growth. It is recommended to regularly clean the eyebrow area to remove excess sebum and debris. Eyebrow transplantation may also be considered under medical advice, which involves extracting healthy hair follicles from the back of the scalp and transplanting them into the eyebrow region to promote natural growth. The typical reference cost for eyebrow transplantation ranges from 3,000 to 5,000 yuan per session. Noticeable improvement generally appears within 1–3 months, though complications such as follicle necrosis or infection may occur.

3. Malnutrition

Long-term picky eating or unbalanced diet leading to malnutrition may impair eyebrow growth, resulting in poor regrowth after shaving. It is recommended to maintain a balanced diet and appropriately supplement vitamins and proteins. Fractional laser therapy may also be administered under a doctor's recommendation, using laser energy to stimulate collagen regeneration and improve skin quality and the eyebrow growth environment. The typical reference cost for fractional laser treatment ranges from 500 to 2,000 yuan per session. Improvement is typically observed within 7–15 days, though possible side effects include hyperpigmentation and allergic reactions.

4. Folliculitis

Failure to maintain personal hygiene during eyebrow removal may result in bacterial skin infections, potentially causing folliculitis. The inflammatory response can damage hair follicles, preventing eyebrow regrowth. Symptoms often include itching and pain. Treatment under medical guidance may include topical medications such as fusidic acid cream, mupirocin ointment, or calamine lotion.

5. Hypothyroidism

Hypothyroidism may be caused by inappropriate medication use, immune system dysfunction, or other factors. Insufficient thyroid hormone secretion can slow down the body's metabolism, leading to the aforementioned symptoms. Additional symptoms may include fatigue, excessive sleepiness, and cold intolerance. Treatment should follow medical advice and may include medications such as levothyroxine sodium tablets, thyroid extract tablets, or propranolol hydrochloride tablets.

Routine eyebrow care is important. Avoid excessive shaving or plucking, and keep the eyebrows and surrounding skin clean to help maintain healthy eyebrow growth.
