Why Hair Changes as We Get Older, Even Before It Turns Gray

Most of us expect our hair to eventually turn gray. What we don’t always expect is everything else it can start doing along the way. In fact, many of you aren’t even aware of the changes your hair is making and instead think you’re doing something wrong.

Maybe the hair you had in your twenties suddenly feels drier. Your curls aren’t curling quite the same way. Your ponytail feels a little smaller. The products you’ve used forever suddenly feel too heavy or not moisturizing enough. Or you swear your hair has become an entirely different texture.

You’re probably not imagining it.

Hair changes throughout adulthood, and those changes can start long before you see your first gray hair.

Your Hair Follicles Change, Too

We tend to think of hair as something that simply grows out of our scalp, but what’s happening at the follicle has a huge influence on the hair we see.

This is a HUGE reason I say, as a hairstylist, to take care of your scalp. It’s the environment your follicles live in.

That doesn’t mean you need a complicated scalp routine. Keep your scalp properly cleansed, pay attention to how it feels, and don’t ignore persistent itching, flaking or irritation. If something seems unusual or isn’t going away, that’s when it’s worth talking to a dermatologist.

As we age, follicles can gradually change. Individual strands may become finer, growth can slow, and the amount of time each hair spends actively growing can shift.

That’s one reason you may notice that your hair doesn’t feel quite as thick as it used to, even if you’re not experiencing obvious hair loss.

Your Texture Can Change

This is the one that surprises people.

Hair that was once straight can develop more wave. Curls can become tighter, looser or simply less predictable. And some people suddenly discover wiry or coarse strands mixed into otherwise soft hair.

Hormonal changes throughout adulthood can influence the follicle and the way hair grows from it. Changes surrounding pregnancy, postpartum, perimenopause and menopause can be especially noticeable, but hair doesn’t wait for one particular birthday to start changing.

Sometimes your hair just isn’t the same hair you had ten years ago.

If you’re noticing a texture change, don’t automatically assume you need more product. Your styling technique may need to change too.

The brush you’ve always used, the way you blow dry, how much tension you’re using, the products you’re combining or even how you’re applying them can all make a difference. If your hair has developed more natural movement, you may get a much better result by learning how to work with it instead of continuing to style it exactly the way you always have.

Your Scalp Changes Along With It

The scalp is skin, and our skin changes as we age.

Oil production can change, which means someone who spent years fighting oily roots may suddenly find themselves needing more moisture. The opposite can happen, too.

That can affect everything from how frequently you want to shampoo to how your styling products behave.

And it explains something I hear all the time:

“I’ve used this forever. Why isn’t it working anymore?”

Sometimes the product didn’t change.

Your hair did.

And sometimes, before replacing your entire routine, your hair just needs a really good reset. Product, minerals and everyday buildup can make hair feel heavier, duller or just off. A good clarifying shampoo every so often can help clear the slate.

My go to for detoxing at home is Bumble and bumble. Sunday Shampoo. It gives you that really clean reset when your hair is starting to feel like nothing is working quite right.

How often you need to clarify depends on your hair, scalp, styling habits and chemical services, so this isn’t necessarily an every wash shampoo.

After that reset, pay attention to what your hair is actually asking for now, not what worked five or ten years ago.

This is another place one of my go to sayings fits:

Your hair is your personal science experiment.

A hair journal can actually help. Pay attention to the days your hair looks and feels its best. What did you wash with? What products did you use? Did you air dry or blow dry? Was it wash day or day three?

Instead of constantly trying something new, start noticing what already works and recreate it.

Density Can Change Before It Looks Like “Hair Loss”

Hair density isn’t necessarily an all or nothing situation.

Individual strands can become finer. Growth cycles can change. Some follicles may produce hair differently than they once did. Those small changes add up.

You might notice it first in a ponytail, around the hairline, through the part or simply in the amount of volume you can create with your regular styling.

That doesn’t automatically mean something is wrong. But significant, sudden or unexplained hair loss is always worth discussing with your doctor or dermatologist rather than assuming it’s simply part of getting older.

Many people think your hairstylist is the expert in this category, but honestly, dermatologists are.

Your hairstylist may be the first person to notice a change because we’re regularly looking at your hair and scalp, but when it comes to figuring out why you’re experiencing hair loss or a significant scalp change, that’s outside our lane.

When Your Gray Hair Feels Like a Completely Different Texture

One of the first things you may notice about gray hair is that it doesn’t always behave like the rest of your hair. Those silver strands can feel coarser, drier or more wiry, which can make them harder to smooth or blend into your usual style.

If that’s happening, don’t assume you suddenly need to coat your entire head in heavier products. Your non gray hair may not need them.

Instead, start by adding moisture where you actually need it. A lightweight leave in conditioner or a small amount of smoothing product through the areas that feel coarse may be enough. If your gray is concentrated around your hairline, you may even need a slightly different approach there than you use on the rest of your hair.

And tell your stylist what you’re noticing. If your texture is changing, we can take that into account when we’re choosing your haircut, products and styling technique.

Your Hair Routine Should Be Allowed to Change

This is probably the biggest thing I wish more people knew.

If the haircut, shampoo, styling product or routine that worked beautifully for you ten years ago isn’t giving you the same result anymore, you haven’t suddenly forgotten how to do your hair.

You may simply be working with different hair now.

And that’s okay.

Sometimes you don’t need an entirely new shelf of products. You just need to rethink what each product is doing for the hair you have today.

If you’re standing in front of your bathroom cabinet wondering where to even start, I broke down the five types of products I think belong in a good hair routine and what each one is actually there to do.

What Order Should You Apply Hair Products? My 5-Product Styling Stack

Start with what has actually changed.

If your hair feels heavy, try clarifying before buying something new.

If it feels drier, look at where you need more moisture.

If your texture has changed, experiment with how you’re styling it.

If it feels finer, make sure your products aren’t weighing it down.

And if something has changed suddenly or significantly, don’t assume it’s just age. Ask someone who can help you figure out what’s actually happening.

Hair changes throughout our lives. The goal isn’t to force it to behave exactly the way it did at 25. It’s figuring out what the hair you have right now needs and giving you a cut, color and routine that work with it.

Because good hair isn’t about trying to keep your hair frozen in time.

It’s about knowing how to work with it as it changes.

Not Sure What Your Hair Needs Now?

If you’re local to San Francisco and you’re reading this thinking, “Okay, but what is MY hair doing?” come see me.

Part of my job as your hairstylist is paying attention to how your hair feels, how it behaves, what you’re doing with it at home and what has changed since I saw you last. Sometimes you need a different product. Sometimes your haircut needs to evolve. Sometimes we just need to change the way you’re styling it.

And sometimes you need someone to tell you that what your hair is doing is completely normal.

Come in, let’s talk about your hair and figure out what makes sense for the hair you have now.
