Hair loss, or alopecia, refers to the process where hair strands fall out from the scalp or body. It’s normal to lose some hair every day, but when shedding becomes excessive, it may signal an underlying issue.
Types of Hair Loss
- Alopecia: A general term for hair loss that includes various conditions.
- Androgenetic Alopecia: Commonly referred to as male or female pattern baldness, it is genetically inherited.
- Telogen Effluvium: A temporary form of hair loss triggered by stress or shock.
- Alopecia Areata: Autoimmune-related hair loss, often presenting as patches.
- Thinning Hair: Hair gradually becomes finer and sparser without distinct bald patches.
When Hair Loss Is Normal vs. Concerning
- Normal Hair Loss: The average person loses 80-120 hairs per day as part of the natural hair growth cycle.
- Excessive Hair Loss: When shedding exceeds the normal range or occurs in patches, it may indicate a more serious issue requiring medical attention.
7 Reasons Your Hair Might Be Falling Out
1 – Genetics
Hereditary hair loss, known as androgenetic alopecia, is one of the most common causes of hair thinning and baldness. Genetics determines whether you’ll inherit this condition and how early it may begin. Both men and women can experience pattern baldness due to genetic factors.
2. Hormonal Changes
Hormonal imbalances can significantly impact hair health. For instance, menopause can lead to a decrease in estrogen and progesterone levels, which are essential hormones for maintaining the hair growth cycle. Postpartum hair loss, pregnancy, and conditions like polycystic ovary syndrome (PCOS) also affect hair shedding.
3 – Stress and Lifestyle Factors
Stress can trigger a condition known as telogen effluvium, where hair prematurely enters the resting phase, leading to significant shedding. Other lifestyle factors such as sleep deprivation, excessive smoking, and alcohol consumption can exacerbate hair loss.
4 – Nutritional Deficiencies
Hair requires a variety of vitamins and minerals to grow. Deficiencies in iron, zinc, biotin, Vitamin D, and protein can result in hair thinning and breakage. Proper nutrition is crucial for maintaining a healthy scalp and promoting hair growth.
5 – Medical Conditions
Certain medical conditions, such as thyroid disorders (both hyperthyroidism and hypothyroidism), can affect hair health. Starting or stopping medications, such as those for blood pressure or birth control, may also trigger hair loss. Autoimmune conditions like lupus and diabetes can lead to excessive shedding or hair thinning.
6 – Medications and Treatments
Hair loss can be a side effect of specific medications, including chemotherapy, antidepressants, and blood thinners. Trauma from surgery or scalp treatments can also affect the hair follicles. Understanding the cause can help in managing hair regrowth post-treatment.
How a Trichologist Can Help
When to Seek Medical Attention for Hair Loss
Hair loss may warrant medical attention when it occurs suddenly, in patches, or is accompanied by other symptoms like itching, pain, or scabbing. If hair thinning persists despite lifestyle changes, it’s time to consult with a professional.
Diagnosing and Treating Hair Loss
A trichologist can diagnose the root cause of hair loss through scalp analysis, blood tests, and reviewing medical history. Understanding whether hair loss is due to genetics, hormonal imbalance, or nutritional deficiencies is key to effective treatment.
Treatment Options
Hair loss treatment may involve dietary recommendations, prescription treatments such as minoxidil (only works when recommended for the correct type of hair loss) or finasteride, scalp therapies, or lifestyle adjustments to reduce stress and improve hair health. Advanced techniques like PRP therapy(Platelet-Rich Plasma) and laser therapy may also be considered to stimulate hair follicles and promote regrowth.
By consulting a trichologist, individuals can receive a tailored approach to treating and preventing excessive hair loss based on their specific condition.
