Have you noticed more hair in your brush or shower drain lately? It may not be your imagination. Scientific research suggests that hair shedding follows a seasonal rhythm, with increased shedding often occurring in late summer and early fall. That makes August and September an especially good time to pay attention to the health of your scalp and hair follicles—and to support the biology behind healthy hair growth.
Your Hair Follicles Change With the Seasons
Hair follicles continuously cycle through periods of active growth (anagen), transition (catagen), rest (telogen), and shedding (exogen). In a classic study published in the British Journal of Dermatology, researchers followed healthy men every 28 days for 18 months and discovered a distinct seasonal pattern in human hair growth.
More than 90% of scalp follicles were in the active growth phase in March. That percentage gradually declined through the summer and reached its lowest point around September. Hair shedding followed the opposite pattern, increasing during the summer and peaking around August and September. At the seasonal peak, participants shed about 60 hairs per day, more than twice the amount observed during the preceding winter months.
So if you’re seeing a little more hair in your shower this time of year, it may simply be part of your follicles’ natural seasonal cycle.
The Important Question Is What Happens Next
Shedding is only one part of the hair cycle. Once a hair is released, the follicle must successfully return to a new growth phase. That process depends on a healthy follicular environment, including hair follicle stem cells, mitochondrial energy production, balanced cellular stress responses, and communication with surrounding cells. This is where the science behind Bluelene Hair Serum comes in.
Bluelene Hair Density Serum: Supporting Hair From the Root
Bluelene Hair Serum was developed from scientific research into methylene blue and cellular resilience and aging. Rather than simply coating or conditioning the visible hair fiber, Bluelene’s approach focuses on the biology at the root of hair. Our research has shown that low concentrations of methylene blue can support mitochondrial function to make more energy needed for hair growth, reduce cellular stress (i.e., caused by UV radiations in the summer month) and reactivate hair growth essential signals. Bluelene Hair Density Serum translates this research into a topical formula designed to support the scalp and follicular environment where healthy hair begins.
Rebuild Hair From the Root
Seasonal shedding is a reminder that healthy hair isn’t static. Every follicle is continually moving through cycles of growth, rest, shedding, and regeneration. That means caring for your hair should be about more than the strands you can see today. Consistent scalp and follicle care can help create an environment that supports the next cycle of healthy hair growth.
For best results, make Bluelene Hair Density Serum part of your regular routine and apply it consistently to the scalp, focusing particularly on areas where you notice thinning or reduced density. Because when it comes to healthy hair, the most important work happens beneath the surface.
