In most cases, it’s androgenic alopecia, which basically means genetic hair loss, and in many cases, it stems from having an unhealthy scalp. “Scalp health is very important to hair health. Oftentimes patients with hair loss have low-grade scalp inflammation that may exacerbate their hair loss. This can be caused by seborrhea, psoriasis, or eczema,” says Dr. Gary Goldenberg of Goldenberg Dermatology in New York City. “Seborrhea and psoriasis are the most common forms of scalp irritation.” Inflammation of the scalp can lead to hair loss because when the follicles become irritated, the hair root is weakened and more hair falls out. That’s where hair loss shampoos can make a major impact. Are these shampoos a silver bullet? No. But they can make your scalp healthier, thus leading to less hair loss. And that’s a win-win.
