Hair loss, known as alopecia, can affect anyone. But what are the causes and symptoms of this hair loss, and how can it be treated? Here’s the essential information.
What Is Hair Loss?
Behind this common issue lie several types of hair loss, each with its own reasons:
- Sudden Occasional Hair Loss (acute telogen effluvium).
- Prolonged Progressive Hair Loss (chronic telogen effluvium).
- Hair Loss Due to Hormonal Issues (androgenetic alopecia).
- Age-Related Hair Thinning (senescent alopecia).
These hair losses result from changes in the hair growth cycle and require specific treatment approaches.
Although hair loss may seem minor, it can cause significant psychological distress. It’s a common reason for dermatological consultation, as it’s not always easy to identify its cause despite common factors.
Occasional Hair Loss
Acute telogen effluvium, also called occasional hair loss, is the most common type. It occurs about 3 to 4 months after a triggering factor, such as stress, emotional shock, fatigue, poor nutrition, or seasonal changes. These factors disrupt the hair
growth cycle, leading to rapid and diffuse hair loss. The loss can reach up to 300 hairs per day, compared to the usual 25 to 60.
Causes of Occasional Hair Loss
- Seasonal Shedding: Like leaves in autumn, hair can fall out in spring and autumn.
- Stress and Fatigue: Emotional shock, intense stress, or anxiety can trigger hair loss.
- Nutritional Deficiency: A diet low in vitamins and minerals weakens hair.
- Post-Childbirth: Pregnancy improves hair quality, but after childbirth, hormonal changes can lead to hair loss.
- Medical Treatments: Some treatments, such as chemotherapy, can cause temporary hair loss.
Chronic Hair Loss
Chronic telogen effluvium, persistent hair loss, can occur at any age, mainly in women. It is triggered by fever, bleeding, surgery, stress, thyroid hormone imbalance, or a strict diet. After eliminating the cause, hair loss may take 12 to 18 months to improve.
Symptoms of Androgenetic Alopecia
Androgenetic alopecia is a progressive hair loss lasting more than 6 months. It is characterized by increasingly fine hair and decreased hair density. This type affects 70 to 80% of men between 30 and 40 years old and 29 to 42% of women between 20 and 40 years old. It is linked to hormonal factors involving androgen receptors in the hair follicle’s dermal papilla.
Age-Related Hair Thinning or Senescent Alopecia
Senescent alopecia occurs after the age of 60. It is characterized by thinner hair, loss of density, and volume in individuals without a family history of hair loss.
Slowing Down Hair Loss
Managing hair loss is challenging because there are few therapeutic options. For chronic telogen effluvium, treatments are available, but for androgenetic alopecia, only slowing down hair loss is possible. Medications like minoxidil and finasteride are available. It’s essential to consult a dermatologist for an accurate diagnosis and treatment recommendations.
At home, use gentle hair care products, avoid vigorous brushing and tight hairstyles, perform daily scalp massage, monitor your diet for adequate vitamins and minerals, and consider dietary supplements during seasonal changes.
In summary, hair loss can have various causes and affects people of all ages and genders. Early consultation with a dermatologist is essential for an accurate diagnosis and treatment recommendations. Proper hair care, a balanced diet, and possibly medication can help slow down hair loss and promote regrowth.
