Differences and Effects of Hair Loss Shampoos and Regular Shampoos

Shampoos used for hair loss treatment are unlikely to provide direct hair loss improvement effects like minoxidil or finasteride.

Because shampoo stays on the scalp for a short time, it has limitations when it comes to allowing key ingredients to penetrate sufficiently.

However, since it is a product used every day, it can have some positive effects.

Therefore, it is important to approach hair loss shampoo as a form of care rather than treatment.

Standards for Being Recognized as a “Hair Loss Shampoo” in Korea

According to the Korean Cosmetics Act, for a shampoo to use the name “hair loss shampoo,” it must contain specific active ingredients and submit supporting data on its efficacy and effects.

The representative recognized ingredients are as follows.

Dexpanthenol: maintains scalp moisture and strengthens the skin barrier to create a healthy scalp environment

Zinc pyrithione: improves scalp health by suppressing dandruff and inflammation

Salicylic acid: has an exfoliating effect, keeping the scalp clean and preventing clogged hair follicles

Products containing one or more of these ingredients can be recognized as “functional cosmetics for hair loss.”

Therefore, when choosing a product, it is important to check whether it contains ingredients suited to your scalp condition.

Additional Ingredients That May Be Included in Hair Loss Shampoo

When choosing a hair loss shampoo, the following ingredients may also provide positive effects.

Saw palmetto: suppresses DHT production and helps prevent hair loss

Things to Keep in Mind When Using Hair Loss Shampoo

1. It is most effective when used in the early stages of hair loss.

2. Use the shampoo twice, and on the second wash, leave it on the scalp for 2 to 4 minutes to allow absorption.

3. Using scalp massage together with it can improve the effect.

4. Ketoconazole shampoo is best used every other day.

5. Avoid using conditioner, or be careful not to let it touch the scalp.

6. Choose products that contain clinically proven ingredients.

7. Use it consistently for at least 2 months before evaluating the effect.

8. Focus on using it to slow the progression of hair loss.

Why There Are No Shampoos Containing Hair Loss Drug Ingredients

The reasons why hair loss drug ingredients such as minoxidil and finasteride are not included in shampoos are as follows.

1. Limitations of Minoxidil Shampoo

Minoxidil promotes hair growth by improving blood circulation around hair follicles, but it must be absorbed into the scalp for at least 24 hours.

In contrast, shampoo stays on the scalp for only about 1 to 3 minutes on average, making sufficient absorption difficult.

Also, there are very few studies proving the effectiveness of minoxidil shampoo, and many previously released products have been discontinued due to insufficient effectiveness.

2. Why Finasteride and Dutasteride Shampoos Do Not Exist

Finasteride and dutasteride suppress hair loss by regulating blood concentration through oral administration.

In shampoo form, sufficient absorption is difficult, and there are concerns about side effects because they may affect sex hormone metabolism.

In addition, shampoos containing these drugs are classified as pharmaceuticals, making regulation and approval procedures strict.

Some positive reviews exist for improving scalp health and strengthening hair

Hair loss shampoo can play a supportive role in hair loss treatment, but it is difficult to expect complete treatment effects from it alone.

When choosing a product, rather than relying on exaggerated advertising, carefully check the ingredients and efficacy, and consistently use a product suited to your scalp condition and the cause of your hair loss.
