8 ways to increase hair density, according to experts

You’ll want to keep in mind that what’s “normal” varies from person to person and is determined by genetics, adds Marcus. And when you notice that your hair density changes significantly from what is normal for you, there may be an underlying issue. “Hair growth occurs in cycles called anagen (active growth phase, about one cm/month, lasts between two and six years); catagen (resting phase – about 3% of scalp hair is in this phase at any given time, lasts between two and three weeks); and telogen (falling phase, about 6% to 8% of scalp hair is in this phase at any given time, lasts about 3.5 months),” explains she. “It’s normal to lose between 50 and 100 hairs a day. This normal hair loss most often occurs when brushing or washing hair, so if someone skips a day or more between washes, they may notice that more hair than usual falls out during their next wash because they didn’t shed the usual amount when they skipped the previous day’s wash.”

Consulting a professional can help you determine if your hair is struggling and what steps to take to improve it. “Any trichology office can offer a hair density check with a device that can measure the density all over your head to see if there are any discrepancies and if your hair is gradually thinning or weakening,” explains Shab Reslan, trichologist and hair expert. “Warning signs of a decrease in hair density include a more visible part of the hair, shorter body hair all over, and a thinner ponytail.”
