Why does my hair
shed more in autumn?

Every October, a familiar pattern emerges. The heat lifts and humidity falls. As you run your fingers through your hair, or check the shower drain or your pillow, you notice more hair shedding than usual.

You assume it's the season with cooler, drier air. And the season is part of it. But the shedding you're seeing in autumn started in summer, and it has been heading your way for months.

The 90-day mechanism

Hair follicles don't operate in real time. When something disrupts them (UV damage, prolonged heat, oxidative stress) the response isn't immediate. Instead, they enter a resting phase called telogen, which lasts approximately 90 days before the follicle releases the hair and the strand falls.

This is the same mechanism behind post-stress shedding, which we've written about here. The logic is identical: the disruption and the visible response are separated by a season. Which means the shedding arriving in October was scheduled in July.

Summer is Pitta season. Pitta is the dosha of fire and heat: it governs metabolism, transformation, and intensity. In summer, Pitta rises in the environment, and it rises in us. UV exposure, heat, and the low-grade inflammation that a full summer accumulates in the body all register as Pitta excess in Ayurvedic terms. The follicle responds by retreating.

The shedding you're seeing in October was scheduled in July.

What autumn adds

Here is where Vata enters.

Autumn is Vata season. Vata is composed of air and space: dry, light, mobile, cool, and rough. These are also the precise qualities that autumn delivers: wind that strips moisture, dropping temperatures, a pervasive dryness in the air and on the skin. When the season shifts into Vata, Vata aggravates. Like increases like. The external qualities amplify whatever Vata you carry internally.

For your hair, this timing is unfortunate. The follicles that summer already pushed into rest now operate in a moisture-depleted environment. The remaining strands themselves become more brittle, drier and more prone to breakage. And because Vata hair tends to be fine, even normal shedding levels look extreme when the remaining hair has less volume and weight.

Two problems, one season

The result is a double whammy that is unique to autumn. First, increased shedding: the deferred consequence of summer excess. Second, increased fragility in whatever remains, because the Vata environment offers hair very little moisture to work with.

These can feel like the same problem, but they're distinct. The shedding is largely already written; the follicles that are resting will release what they're holding. What you can do now is support the follicles that are still in an active growth phase, creating better conditions for what's coming in.

The ingredients Ayurveda recommends

The botanicals Ayurveda has long prescribed for Vata elevation in autumn are the same ones that address the depletion driving seasonal shedding. Ashwagandha and shatavari — the two primary Ayurvedic adaptogens — build systemic resilience and are used traditionally to prevent hair loss patterns from compounding under stress and seasonal strain. Both have documented effects on cortisol regulation and nervous system recovery, making them directly relevant to the telogen effluvium pattern that stress and seasonal transitions can trigger. Black cumin seed oil (Nigella sativa) has a centuries-long place in Ayurvedic scalp practice: warming, stimulating, and documented for its effects on follicle health and anagen retention — precisely what a follicle coming out of a stress-induced rest phase needs. Mango butter and panthenol address moisture at the shaft level, keeping the cuticle sealed against the drying autumn air that amplifies Vata through the season.

The traditional practice combines these as a warming pre-wash oil — ashwagandha-infused sesame or black cumin, applied with massage and left for thirty minutes before washing. It works. It is also time-consuming to prepare and sustain consistently through the season. ARCIS Vata delivers these ingredients — ashwagandha, shatavari, black cumin seed oil, mango butter, panthenol — in a solid bar that activates with water and rinses clean. The essential oil profile (cardamom, rose, frankincense) was chosen to be warming and grounding: the sensory counterpart to what the botanicals are doing constitutionally.

Working with the season

Autumn asks for a different relationship with your hair than summer does. Where summer requires protection from heat and UV, autumn requires feeding: oil, warmth, and shelter from wind and cold.

Scalp oiling becomes more important, not as a cosmetic ritual but as a functional response to a dry environment. The scalp is where the follicle lives; keeping it supple improves the conditions for growth. Warm oil penetrates better than cold, and gentle massage improves circulation to follicles dormant all season.

Reducing heat styling in autumn is also more important than it sounds. Vata is already dry and airy. Adding more heat works against the season rather than with it. If the goal is to hold moisture, the tools that strip it are working against you.

And for Vata types in particular, those whose constitution already tends toward dryness, fine strands, and volatility, autumn is the season to be deliberate. Environmental and constitutional Vata factors can compound quickly. The practices that barely register in summer can make significant differences now.
