Hair Loss: Is Your Shampoo or Styling Technique to Blame? - Dermatology

Hair issues


Hello doctor, I would like to ask a question.
In mid-August, I had a perm, and to maintain the volume of my hair, I followed a method I found online where I blow-dry my hair and then apply localized heat to the top of my head to create volume.
Previously, this method didn’t cause any issues, but now that I’ve moved to a new place and switched to a different variant of the same brand of shampoo, I’ve noticed that my hair has been shedding more than usual over the past 3 to 4 days.
Is this a problem with the shampoo, or could it be that I was holding the hairdryer too close to my scalp when applying heat? I typically keep the hairdryer about 5 to 10 centimeters away from my scalp and use the highest heat and airflow setting, but I don’t focus on one spot for too long.
Am I at risk of damaging or even killing my hair follicles? I’m really worried about going bald.
Thank you for your response, doctor.

Hair loss can be a distressing experience, and understanding its causes and potential treatments is crucial for anyone facing this issue. Based on your concerns, let's break down the possible reasons for your increased hair shedding and discuss the implications of your hair care routine.

Firstly, it's important to recognize that hair loss can be influenced by a variety of factors, including genetics, hormonal changes, environmental conditions, and hair care practices. In your case, you mentioned a recent change in shampoo and a new hair styling technique involving heat. Both of these factors could potentially contribute to your hair loss.

1. Shampoo Change: Switching to a different formulation, even within the same brand, can sometimes lead to unexpected reactions. Some shampoos contain sulfates, parabens, or other harsh chemicals that can irritate the scalp or weaken hair strands, leading to increased shedding. If you notice that your hair is falling out more after using a new shampoo, it might be worth considering whether the ingredients are suitable for your hair type and scalp condition. Look for gentle, sulfate-free shampoos that are designed for sensitive scalps or hair loss.

2. Heat Styling: Using heat to style your hair can also have detrimental effects if not done carefully. While blow-drying can add volume, excessive heat can damage the hair shaft and lead to breakage. Keeping the blow dryer 5-10 centimeters away from your scalp is a good practice, but using the highest heat setting can still pose a risk. It’s advisable to use a lower heat setting and to keep the dryer moving to avoid concentrating heat in one area for too long. Additionally, using a heat protectant spray can help shield your hair from damage.

3. Potential for Follicle Damage: Concerns about damaging hair follicles are valid. Prolonged exposure to high heat can indeed harm the hair follicles, potentially leading to hair thinning or loss. However, if you are experiencing increased shedding, it may not necessarily mean that your follicles are permanently damaged. Hair shedding can occur due to a variety of temporary factors, including stress, changes in routine, or even seasonal variations.

4. Psychological Factors: It's also worth noting that anxiety about hair loss can exacerbate the situation. Stress can lead to a condition known as telogen effluvium, where hair follicles prematurely enter the shedding phase. If you find yourself overly worried about hair loss, it might be helpful to engage in stress-reducing activities such as exercise, meditation, or speaking with a mental health professional.

5. When to Seek Help: If the increased hair loss persists or worsens, it may be beneficial to consult a dermatologist or a trichologist. They can assess your scalp and hair health, conduct necessary tests, and recommend appropriate treatments. Early intervention is key, especially if there are signs of scalp irritation or if hair loss is accompanied by other symptoms like redness or itching.

In conclusion, while changes in shampoo and heat styling techniques can contribute to hair loss, it’s essential to consider the broader context of your hair care routine and overall health. Monitor your hair loss closely, and if it continues or worsens, seek professional advice to explore potential underlying causes and treatment options. Remember, taking care of your hair and scalp with gentle products and techniques can help maintain their health and appearance.
