How Seasonal Changes Affect Hair Loss (And How to Protect Your Hair Year-Round)

Have you ever noticed more hair falling out during certain times of the year? Maybe it’s in the shower drain or stuck in your hairbrush. If that sounds familiar, you’re not alone! Seasonal hair loss is a real thing, and yes, the weather in San Jose (and beyond) can play a big part.

Let’s take a closer look at how the seasons affect your hair—and what you can do to keep it strong and healthy all year long.

Why Does Hair Fall Out More in Certain Seasons?

Just like animals shed their fur, humans can shed more hair during certain times of the year. This is called seasonal shedding, and it’s totally normal.

Here’s what usually happens:

🍂 Fall and Winter

• You may notice more shedding during cooler months.

• Less sunlight can lower your vitamin D levels, which are important for hair growth.

• Cold, dry air can make your scalp dry and itchy, leading to more breakage.

🌸 Spring and Summer

• Warmer weather may improve blood flow to your scalp.

• However, sun exposure, chlorine, and humidity can dry out or damage hair.

• Sweating more can clog pores on your scalp, which might affect growth.

So yes—each season brings its own hair challenges. But don’t worry—there are simple ways to protect your hair every month of the year.

How to Protect Your Hair Year-Round

Keeping your hair happy and healthy means adjusting your routine as the seasons change. Here are some tips you can follow right here in San Jose—or wherever you are:

🧴 Fall & Winter Hair Tips

• Use a moisturizing shampoo and conditioner to fight dryness.

• Add a scalp oil or treatment to soothe itchy skin.

• Wear a hat or scarf when it’s windy or cold to protect strands.

• Consider a vitamin D supplement—ask your doctor first.

🌞 Spring & Summer Hair Tips

• Wear a hat to protect your scalp from sunburn.

• Use a UV protectant spray if you're out in the sun a lot.

• Rinse your hair after swimming in a pool or the ocean.

• Keep hair tied loosely to prevent tangles and breakage.

Is It Normal to Lose More Hair in the Fall?

Yes! Research shows that people often shed more hair in the fall—especially in September and October. This is usually part of the natural hair growth cycle and should balance out after a few months.

But if your hair is thinning quickly, falling out in clumps, or you see bald patches—it could be something more serious. In that case, it’s a good idea to talk to a hair and scalp specialist, also known as a trichologist.

When to Ask for Help

If your hair loss is making you feel stressed or self-conscious, don’t wait. Seasonal shedding is normal—but sometimes it can be a sign of something else, like:

• Hormonal changes

• Poor nutrition

• Stress

• Scalp issues

• Hereditary hair loss
