Your Hair Follows a Cycle
Hair grows in cycles. The anagen phase is when hair actively grows. The catagen phase is the transition phase when growth slows. The telogen phase is the resting phase when hair naturally sheds to make room for new growth.
At any time about 10 to 15 percent of your hair is in the shedding phase. Seasonal changes can push more hairs into this phase at once. This is why you may be noticing extra strands.
Seasonal Shedding Is Real
Research shows hair shedding often peaks in late summer and early autumn. Some people also notice small increases in spring. This is part of your hair’s natural rhythm and not a sign of damage.
Seasonal shedding happens for a few reasons. Changes in daylight and temperature can signal hair follicles to adjust growth. Hormonal shifts related to seasons may influence shedding. Hot, humid summers or dry, cold winters can make hair more prone to breakage.
What Is Normal
Even with seasonal shifts, losing 50 to 100 hairs a day is normal. Seasonal shedding may add a few more, but it is temporary. Your hair will bounce back as the seasons settle.
What Is Not Normal
Certain signs mean it is worth checking with a dermatologist. Sudden, excessive hair loss that does not slow down. Bald patches or thinning spots. Shedding that affects your overall volume significantly. Hair breakage with scalp irritation, redness, or flaking.
These signs may indicate underlying issues like hormonal imbalances, nutrient deficiencies, stress, or scalp conditions rather than seasonal changes.
