There are a few ways to tell if a product is working to stimulate hair growth:
-
Visible signs of hair growth: One of the most obvious signs that a product is working to stimulate hair growth is seeing new hair growth in areas where there was previously little or no hair. This can take several weeks or months to become noticeable, so it's important to be patient and consistent in using the product.
-
Reduction in hair loss: If a product is effective at stimulating hair growth, it may also help to reduce hair loss. Over time, you may notice less hair falling out when you brush or wash your hair.
-
Improved hair thickness and quality: Another sign that a hair growth product is working is an improvement in the thickness and quality of your hair. If your hair feels stronger, healthier, and looks more voluminous, this may be a sign that the product is working to stimulate hair growth.
-
Scientific evidence: Finally, it's important to look for scientific evidence to support the claims of a hair growth product. Look for clinical studies or other research that shows the product has been tested and found to be effective at stimulating hair growth.
