Finasteride is a common drug for treating androgenetic alopecia. Compared with oral administration, the topical preparation can reduce systemic side effects and is more suitable for patients seeking a milder treatment.
Pre – medication Preparation
Scalp Cleaning
Wash the hair and scalp with a mild shampoo to remove oil, dirt, and dandruff. After washing, gently dry the scalp with a towel to ensure it is dry. This allows the drug to better contact and be absorbed by the scalp. For example, if you plan to use the drug in the morning, you can clean your hair and scalp during your morning wash. If you use it at night, complete the cleaning before going to bed.
Scalp Condition Check
Examine whether there are any abnormal conditions on the scalp, such as breaks, inflammation, ulcers, or allergies. If any of the above problems exist, 暂停使用 (suspend use) and consult a doctor, as these conditions may affect drug absorption and even exacerbate adverse reactions.
Specific Usage Steps
Drug Withdrawal
Squeeze an appropriate amount of topical finasteride solution into the palm according to the drug instructions or the doctor’s advice. Generally, the dosage per time is about 1ml. You can adjust it appropriately according to the size of the hair – loss area, but do not arbitrarily increase or decrease the dosage on your own.
Application
Evenly apply the solution to the hair – loss area on the scalp, and gently massage with your fingertips to ensure the drug fully covers the scalp. When massaging, be gentle. Start from the center of the hair – loss area and spread it outwards. The massage time is about 3 – 5 minutes to promote drug penetration. For example, if you have hair loss on the top of your head, concentrate the drug application on the top of the head and massage in the above – mentioned way.
Hand – washing
After using the drug, be sure to thoroughly wash your hands with soap and water to prevent drug residues from contaminating other parts, especially mucous tissues such as the eyes and mouth, to avoid irritation.
Usage Frequency and Duration
Frequency
It is usually recommended to use it once a day at a fixed time to ensure a stable blood drug concentration in the body and achieve the best therapeutic effect. If you are used to using it in the morning, apply it at the same time every morning. If you choose to use it at night, use it on time every night.
Duration
Topical finasteride takes effect relatively slowly. Generally, it needs to be used continuously for 3 – 6 months to see obvious effects. Therefore, you need to be patient and persistent. Do not stop using the drug casually in the middle, otherwise it may affect the treatment process and the final effect.
Precautions
Avoid Contact with Other Parts
During the medication process, avoid the drug from coming into contact with the skin of other parts such as the face and neck to prevent abnormal hair growth in these areas. Once it accidentally comes into contact, immediately rinse with a large amount of water.
Pregnant and Breastfeeding Women
Pregnant women are strictly prohibited from coming into contact with finasteride. Breastfeeding women should also avoid using it to prevent the drug from being transmitted to the baby through breast milk. When there are pregnant or breastfeeding women in the family, keep the drug properly in a place where they cannot reach it.分享
