Is your comb not the cause of hair problems? Often we use expensive products to keep hair healthy, but even then the results are not good. Have you ever thought that the reason for this may be your dirty-comb. Due to not cleaning the comb, dirt accumulates in it, which causes bacteria to grow in it. Bacteria in the comb can cause fungus, itching, infection in your scalp. Not only this, if you use a dirty-comb for a long time, then the hair product used on the hair will come back to your hair from the comb and there may be further complaints of hair loss or baldness. To avoid this, clean your comb 2 times a week by pouring it in hot water and keep it disinfected.
