Hair Loss: Is It Normal Shedding or Male Pattern Baldness?

Male pattern baldness

Hello Dr.
Zheng, I am a patient with early-stage androgenetic alopecia and have bilateral receding hairlines.
I am undergoing low-level laser therapy.
I have oily hair, so I wash my hair frequently; however, I notice some hair loss during washing and drying.
What I want to know is whether the hair loss is due to the end of the "anagen phase" or if it is caused by "androgenetic alopecia." If it is the latter, will the hair that has fallen out have a chance to regrow due to the low-level laser therapy?

Understanding hair loss can be a complex issue, especially when distinguishing between normal shedding and conditions like male pattern baldness (androgenetic alopecia). Given your description of having receding hairlines on both sides, it appears you are experiencing early signs of male pattern baldness. This condition is characterized by a gradual thinning of hair, typically starting at the temples and crown of the head, and is influenced by genetic and hormonal factors.

Normal hair shedding is a part of the hair growth cycle, which consists of three phases: anagen (growth), catagen (transition), and telogen (resting). On average, it is normal to lose about 50 to 100 hairs a day. However, if you are noticing an increase in hair loss, especially in conjunction with the receding hairline, it may indicate that the hair follicles are miniaturizing due to male pattern baldness.

In your case, the use of treatments like Minoxidil (often referred to by brand names such as Rogaine) can be beneficial. Minoxidil works by stimulating hair follicles and prolonging the anagen phase of the hair growth cycle, which can lead to new hair growth in some individuals. However, it is important to note that results can vary from person to person. Some may experience significant regrowth, while others may see minimal improvement.
If the hair loss you are experiencing is indeed due to male pattern baldness, the hair that has already fallen out may not grow back on its own. However, with consistent use of Minoxidil, there is a possibility that new hair can grow in areas where follicles are still active but have been weakened. It is crucial to be patient, as it may take several months to see noticeable results from the treatment.

Additionally, it is essential to maintain a healthy scalp environment. Since you mentioned having oily hair, ensure that you are using a gentle shampoo that can help manage oiliness without stripping the scalp of necessary moisture. Over-washing can sometimes lead to irritation, which may exacerbate hair loss.

If you have concerns about the effectiveness of your treatment or if you notice any unusual symptoms, such as itching, redness, or excessive shedding, it would be wise to consult with a dermatologist or a trichologist. They can provide a thorough evaluation and may suggest additional treatments or lifestyle changes that could help manage your hair loss.

In summary, while some hair shedding is normal, the pattern and extent of your hair loss suggest that you may be experiencing male pattern baldness. Treatments like Minoxidil can potentially help stimulate new hair growth, but results vary. Consistent use and proper scalp care are key components of managing your hair loss effectively. If you have further questions or concerns, don't hesitate to reach out to a healthcare professional for personalized advice.
