- **Treatment of hypertension** (oral, less used): lower blood pressure.

### **3. Dosage and use**

#### **Topical dosage (treatment of hair loss)**

- **Recommended concentration**:

- Men usually use 5% solution or foam;

- Women generally use 2%-5% solution.

- **Daily frequency of use**: It is recommended to apply 1 mL to the hair loss area of ​​the scalp twice a day (once in the morning and once in the evening).

- **Precautions**:

- Avoid applying to other parts of the skin to prevent excess hair growth.

- **Half-life**:

- For external use: about 4 hours.

- For internal use: about 3-4 hours.

- **Excretion**: mainly excreted through urine, mainly in the form of metabolites.

### **5. Usage cycle and effect**

- **External use cycle**:

- **Initial effect**: After 4-6 weeks of continuous use, there may be a temporary increase in hair loss ("hair loss period"), which is a normal phenomenon.

- **Significant effect**: It takes 3-6 months of continuous use to observe a significant increase in hair.

- **Maintenance period**: Long-term use (at least 1 year or more) can maintain the effect.

- **Oral cycle**:

- According to the specific condition, it is determined by the doctor, and blood pressure and cardiovascular status need to be monitored regularly.

### **6. Precautions**

*Minoxidil Raws Powder is a raw material for treating hair loss and promoting hair growth, and is often used to prepare topical drugs. The following is a detailed introduction to its applicable population, working principle, and usage and dosage:

### **Applicable population**

1. **Male pattern hair loss (androgenic alopecia)**

Mainly for male hair loss problems on the top and forehead caused by genetic or hormonal changes.

2. **Female pattern hair loss**

Suitable for women with diffuse hair loss, especially when the top of the head is sparse.

3. **Other types of hair loss patients**

Including alopecia areata or hair loss caused by non-genetic factors (such as stress, disease or drug side effects), may be used under the guidance of a doctor.

4. **Patients who cannot improve hair loss by other means**

Especially those who cannot improve with nutritional supplements, scalp care or other therapies.

### **How ​​it works**

Minoxidil's main mechanism of action is as follows:

1. **Promote vasodilation**

Minoxidil can dilate blood vessels around local hair follicles, increase blood circulation, and improve oxygen and nutrient supply to hair follicles.

2. **Extend the growth phase of hair follicles**

Minoxidil can activate the growth cycle of hair follicles, allowing hair follicles in the resting phase to re-enter the growth phase, thereby promoting hair regeneration.

3. **Increase hair follicle activity**

By directly stimulating hair follicle cells, improving their metabolism and proliferation capabilities, and enhancing hair density and thickness.

4. **Improve scalp environment**

Reduce excessive oil secretion caused by hair loss on the scalp and create an environment conducive to hair growth.

### **Usage and Dosage**

Minoxidil Raws Powder is usually prepared as a topical liquid (such as Minoxidil solution or foam) before use. Common usage and dosage are as follows:

1. **Topical method**

- Use a dropper or spray to evenly apply the Minoxidil solution to the scalp in the area of ​​hair loss, avoiding applying it to the hair.

- Gently massage the scalp with your fingertips to help the drug absorb.

2. **Dosage recommendation**

- **Men**: It is recommended to use 1ml Minoxidil solution (usually 5% concentration) once a day, once in the morning and once in the evening.

- **Women**: It is recommended to use 1ml Minoxidil solution (usually 2% or 5% concentration) daily. The specific concentration needs to be consulted by a doctor according to the hair loss situation.

3. **Continuous use**

- **Initial effect**: It takes about 3-4 months of continuous use to see obvious results.

- **Long-term maintenance**: Stopping use may cause hair to fall off again, so it is recommended to use it for a long time to maintain the effect.

4. **Precautions**

- Avoid excessive use or frequent increases in dosage to avoid side effects (such as scalp irritation or hypotension).

- Avoid use if there is a wound, infection or increased sensitivity on the scalp.

### **Special Reminder**

- **Contraindications**: People with scalp diseases, cardiovascular diseases or allergies to Minoxidil should not use it.

- **Pregnant and lactating women**: Must consult a doctor before use.
