It is widely accepted that losing 50 to 100 hairs per day is a normal part of the hair growth cycle. While the claim correctly identifies this range as a baseline, it is slightly overstated to suggest that exceeding this number is a definitive indicator of an underlying health issue. Increased shedding can be a temporary, benign response to various triggers like stress, illness, or hormonal shifts (often called telogen effluvium), rather than a sign of a chronic medical condition. Because individual hair density and styling habits vary, the most reliable indicator is a noticeable change in your own personal pattern—such as thinning, widening parts, or bald patches—rather than a strict count of strands.

Brushing hair 100 times daily causes physical breakage and damage.
overstatedThe "100 strokes" rule is a historical relic from an era when people washed their hair infrequently and relied on mechanical brushing to distribute scalp oils (sebum) down the hair shaft. In the context of modern hair care, this practice is unnecessary and often counterproductive. While brushing is useful for detangling and removing loose hairs, excessive, repetitive strokes create cumulative friction that can damage the hair's protective cuticle, leading to frizz, split ends, and mechanical breakage. The damage is not immediate but accumulates over time, particularly for those with fragile, curly, or chemically treated hair. There is no evidence that 100 strokes provide any functional benefit to hair health; once detangling and oil distribution are achieved—typically in 10–25 strokes—further brushing only adds wear and tear.
Applying olive oil to the scalp promotes the growth of yeast associated with dandruff.
holds upThe claim is well-supported by dermatological understanding of the scalp microbiome. *Malassezia* yeast, which is commonly associated with dandruff and seborrheic dermatitis, relies on external lipids to survive and proliferate. Olive oil contains fatty acids that *Malassezia* can metabolize, effectively acting as a food source that may encourage yeast overgrowth in susceptible individuals. While some people use olive oil for dry scalp, it is generally advised to avoid it if the underlying cause of flaking is fungal, as it can exacerbate inflammation and symptoms.

A decrease in the overall density of your hair can be a telltale sign of ongoing hair loss.
