The Root of Modern Hair Thinning: A Disrupted Hair Growth Cycle

So, what was the inspiration behind developing a medicated hair growth serum in the first place?

"After digging into the issue of hair thinning, a major concern for many people today, we discovered that it's often linked to a disrupted hair growth cycle. Factors like stress, lack of sleep, aging, hormonal imbalances, scalp buildup, and poor circulation can all throw this cycle out of whack, leading to hair loss, finer strands, and a lack of volume."

The "hair growth cycle" is the crucial element here.

Over a roughly six-year period, your hair cycles through three phases: anagen (growth), catagen (transition), and telogen (resting), before shedding and starting anew. When this cycle is disrupted—for instance, if the growth phase becomes shorter—it can lead to thinning and hair loss.
