Hair Loss and Regrowth: Expert Answers to Common Concerns

Hair loss and hair growth issues..?

Hello, doctor.
I have a few questions:
1.
I have oily hair, and if I don’t wash it for more than two days, it looks greasy but not shiny.
Therefore, for the past five or six years, I have maintained a habit of washing my hair daily.
However, I use soap instead of shampoo.
Will washing my hair every day and using soap harm my scalp or hair follicles?
2.
I have the impression that about three or four years ago (or perhaps even earlier without noticing), the hair in the whirl on the top of my head seemed to be thinning, but I didn’t pay much attention to it.
It wasn’t until the last year or two that I felt the amount of hair loss seemed to increase, and the regrowth of new hair appears to be slow.
Now, my hair is sparse, and I can see my scalp, which has raised concerns among my friends and family.
Due to my work, my schedule is not very regular, and if this is a cause of significant hair loss, my other colleagues have thick hair on their heads.
The thinning hair has been quite distressing for me.
Could you please give me some advice?
3.
Some people say that frequently getting a buzz cut will make hair grow thicker and more abundant (similar to how shaving facial hair makes it grow back thicker).
Is this true? If I get a buzz cut, will the areas where my hair is thinning gradually return to normal?
4.
Since I haven’t seen much new hair growth for a long time, does this mean my hair follicles might be dying? Is there still a chance for hair to grow back? Can I buy products like Rogaine or other hair growth treatments myself? Are they effective?
5.
Does wearing a full-face helmet while riding to work every day contribute to my hair problems? I have several questions, and I hope you can help clarify them so I can regain my attractive appearance.
Thank you!

Hello,
In response to your inquiry, regarding scalp cleansing products, there is no specific formulation that is required; as long as the cleansing power is appropriate and can effectively remove oil and dirt from the scalp without causing harm, it is considered suitable for individual use.
Generally, soap-based products tend to be more alkaline, which may provide stronger cleansing but could also lead to irritation of the scalp, face, and eyes.
Using bar soap throughout the year, especially in winter when sebum production is lower, may result in excessive dryness.
It is advisable to select appropriate products and use them as needed.
For hair loss treatment, it is essential to establish a diagnosis first.
This requires an in-person examination of the scalp and hair, along with a review of medical and family history.
If necessary, blood tests or scalp biopsies may be performed to obtain further information.
If you are genuinely concerned (e.g., whether hair follicles are still present, whether the condition is worsening, etc.), it is recommended that you seek medical attention promptly to avoid delays that could lead to irreversible damage.
Best wishes,
Dr.

Understanding hair loss and regrowth can be a complex issue, especially when it involves various factors such as genetics, lifestyle, and hair care practices. Let’s address your concerns one by one.

1. Daily Washing and Soap Use: Washing your hair daily, especially with soap instead of shampoo, can potentially harm your scalp and hair follicles. Soap is typically more alkaline than shampoo, which can strip the natural oils from your scalp and hair, leading to dryness and irritation. This can result in an unhealthy scalp environment, which may contribute to hair loss. If you have oily hair, consider using a gentle, sulfate-free shampoo designed for daily use. This will help maintain a healthy balance of oils while effectively cleansing your hair.

2. Noticing Thinning Hair: It’s common for individuals to notice changes in their hair density over time, particularly in areas like the crown. Stress, irregular work hours, and lifestyle factors can significantly impact hair health. Chronic stress can lead to a condition called telogen effluvium, where hair follicles prematurely enter the shedding phase. It’s crucial to address these lifestyle factors, as managing stress through relaxation techniques, regular exercise, and a balanced diet can promote healthier hair growth. If you notice significant thinning, it may be wise to consult a dermatologist or a trichologist for a thorough examination and personalized advice.

3. Haircuts and Hair Growth: The idea that frequent haircuts can make hair grow thicker or faster is a common myth. Hair growth occurs at the follicle level beneath the scalp, and cutting hair does not influence this process. However, regular trims can help maintain the health of your hair by preventing split ends and breakage, which can make your hair appear fuller and healthier. If you’re experiencing thinning, a shorter hairstyle may also help you manage the appearance of your hair.

4. Hair Follicle Health: If new hair hasn’t grown in a long time, it may indicate that the hair follicles are not functioning optimally. However, this doesn’t necessarily mean they are dead. Hair follicles can remain dormant for extended periods and may reactivate under the right conditions. Products like minoxidil (often found in Rogaine) can stimulate hair growth in some individuals, but results can vary. It’s advisable to consult a healthcare professional before starting any treatment to ensure it’s appropriate for your specific condition.

5. Impact of Wearing a Helmet: Wearing a full-face helmet daily can contribute to hair issues, particularly if it causes friction or excessive sweating on the scalp. This can lead to conditions like folliculitis or exacerbate existing scalp issues. To mitigate this, ensure that your helmet fits properly and is well-ventilated. Additionally, consider taking breaks from wearing the helmet when possible to allow your scalp to breathe.

In conclusion, hair loss can stem from a variety of factors, including genetics, stress, hair care practices, and overall health. It’s essential to adopt a holistic approach to hair care, focusing on gentle cleansing, stress management, and proper nutrition. If your hair loss continues or worsens, seeking professional advice from a dermatologist or trichologist can provide you with tailored solutions and treatments to help restore your hair health. Remember, early intervention is often key in managing hair loss effectively.
