The Best Hair Advice for Your Period: Decoding Your Cycle’s Impact on Your Scalp

You know the feeling: you’re trying to styles your hair for an important event, but it just won’t cooperate. It’s either flat, oily, or unusually dry—and you realize, "Oh, my period is coming."

At Bloom, we view your body as a Biological Symphony. When your hormones shift, the music your body plays changes—and that includes the hair on your head. 🧬🎼

Let’s decode the science of how your cycle impacts your scalp and how you can find your natural shine throughout the month.

1. The "Oily" Phase (Your Cycle’s Autumn)

In the days leading up to your period (the "Autumn" phase), your body experiences a peak in progesterone. This increase in hormones, along with a slight rise in androgens, can trigger your sebaceous glands to produce more oil (sebum).

The Symptoms: An oily scalp, hair that feels flat or weighed down, and even scalp breakouts. The Solution: Use a clarifying shampoo once a week during this phase to gently detoxify your scalp without stripping its natural moisture.

2. The "Dry" Phase (Your Cycle’s Winter)

When your period finally arrives (the "Winter" phase), your levels of estrogen and progesterone drop to their lowest point. Without a healthy dose of estrogen to maintain hydration, your hair and skin can start to feel dry and even brittle. ❄️💎

The Symptoms: Dullness, lack of shine, and strands that feel thirsty for moisture. The Solution: This is the perfect time for a deep-conditioning hair masque. Look for botanical oils that nourish the hair cuticle while your body focuses on its internal reset.

3. The Iron Connection (Hair Shedding)

If you notice more hair than usual in your brush during your period, don’t panic. While some shedding is normal, intense shedding can be linked to iron deficiency. Your period uses up your body’s iron stores, and iron is essential for the oxygen supply to your hair follicles. 🧬📉

The Symptoms: Feeling of hair thinning or excessive shedding during heavy period days. The Solution: Focus on iron-rich foods like spinach and legumes. Tracking the intensity of your period in the Bloom App can help you see if there’s a pattern between heavy flow and hair health.
