As I turn 45, I can feel my hair starting to thin. This has led me to think a lot about shampoo.

In the past, I would just pick whatever was on sale at the store, but at some point, my hair became dry and my scalp became sensitive.

So, when I see advertisements, I find myself swayed.

When I read phrases like damage repair, scalp care, and salon-quality treatment, I start to wonder if I need to use more expensive products.

In short, I find myself questioning whether I should buy a shampoo that costs $30-40 instead of the usual $8.

However, experts say that expensive shampoos are not necessarily better.

Relatively inexpensive products sold at grocery stores or pharmacies can do their job just fine.

What matters is not the price or brand, but the ingredients and the condition of your scalp.

Shampoo is more of a product for scalp care than for hair itself, which is a fact I was unaware of.

Once hair emerges from the skin, it is biologically inactive.

In contrast, beneath the scalp, there are various structures like hair follicles, sebaceous glands, and immune cells.

If this environment is balanced, the scalp feels comfortable and hair grows healthily.

However, if the balance is disrupted, issues like itching, dandruff, excess oil, and hair loss can occur.

Therefore, when choosing a shampoo, it's important to first assess the condition of your scalp.

It's necessary to determine whether it's oily, dry, or sensitive.

If you have dandruff or itching, products with antibacterial or anti-inflammatory properties can be helpful.

If you frequently dye or perm your hair, it's best to use products that are gentle and moisturizing.

This choice is not necessarily related to price.

Experts emphasize that the most important factor is not the product but the care habits.

How often you wash your hair, how much you use a hairdryer, and how frequently you dye or perm your hair have a greater impact on the condition of your scalp and hair. If you have very curly or dyed hair, it's better not to wash it too often. Conversely, if you have straight hair with an oily scalp, washing it daily is fine.

Ultimately, healthy hair starts with lifestyle habits rather than expensive products.

Not all expensive products are unnecessary. Some may use specific functional ingredients or organic materials that justify their higher price. Additionally, some products may work better for certain individuals. However, there's no need to switch all products to high-end lines. You can achieve good results by using cost-effective shampoos and selecting functional products only for treatments or conditioners.

As I enter my 40s, I find that instead of choosing products based on brand, I first check if they suit my condition.

What matters is not the price, but whether my scalp feels comfortable and if my hair improves after use.

Advertisements promise hair improvement, but the real change comes from care habits.

The conclusion is that a single shampoo won't completely change your hair. However, by understanding your scalp condition and making slight adjustments to your care routine, you can expect positive changes.

Choosing the right products for yourself and adopting proper care habits seems to be the wiser approach than just looking for expensive products.
