Many people wonder, “Do hair regrowth products really work?” or “Which hair regrowth product is right for me?”
Hair regrowth products are an accessible way to start addressing hair thinning, but to achieve the desired results, they must be used correctly.
In this article, we explain the effects of hair regrowth products, how they differ from hair growth products, essential knowledge you should know, and tips on how to choose and use the right product for you.
Hair regrowth products are topical treatments applied directly to the scalp that stimulate new hair growth. Their main ingredient, minoxidil, is a widely used and clinically proven treatment for hair thinning worldwide.
What Is Minoxidil?

Minoxidil was originally developed as a medication to lower blood pressure. However, a side effect of increased hair growth led to its use in hair loss treatments.
Minoxidil works by dilating blood vessels in the scalp, improving blood flow. This directly stimulates the hair follicles, helping to extend the growth phase of the hair cycle, promote new hair growth, and prevent hair loss.
The effectiveness of minoxidil is supported by strong clinical evidence. The Japanese Dermatological Association ranks its recommendation at the highest level on a five-point scale, and recommends applying 5% minoxidil topically for male pattern hair loss.
Side Effects of Hair Regrowth Products
While hair regrowth products can be effective for thinning hair, there is a possibility of side effects. According to a survey by Japan’s Ministry of Health, Labour and Welfare, the probability of experiencing side effects is 8.82%.
Side effects do not occur in everyone, and symptoms vary by individual. The most common effects include scalp itching or irritation, caused by the active hair growth ingredient, minoxidil.
Since minoxidil was originally developed as a blood pressure medication, it may also cause headaches, dizziness, or other systemic effects. People being treated for high or low blood pressure, or with existing heart conditions, should consult a doctor or pharmacist before use, as there is a risk of cardiovascular side effects such as heart attack or angina.
To reduce the risk of side effects, it is important to follow the recommended dosage and instructions. If you experience any concerning symptoms, stop use immediately and consult a physician.
Does Hair Fall Increase When Starting a Topical Treatment?

It is common to experience increased hair shedding when first starting a hair regrowth product. This phenomenon is called “initial shedding”.
Initial shedding occurs because old hairs must fall out to make room for new hair to grow.
Although this can be alarming, discontinuing use prematurely may prevent you from seeing results. Therefore, it is important to continue using the product even if initial shedding occurs.
Differences Between Hair Regrowth Products and Hair Growth Products
Hair regrowth products and hair growth products differ significantly in both purpose and effects.
Hair Regrowth Products
Hair Growth Products
Both types are available at drugstores and online. The main difference lies in minoxidil, an ingredient found only in hair regrowth products, which provides the ability to stimulate new hair growth.
The choice between hair regrowth and hair growth products depends on your specific concerns and goals.
