Hi, Tugain Foam 5% contains minoxidil and is used to promote hair growth in individuals with androgenetic alopecia (male pattern baldness). It is usually recommended to use it twice daily for at least 4 to 6 months to see any noticeable results. However, the duration of use can vary depending on the individual s response to treatment and the severity of the condition. Regarding the use of Dutasteride (Dutas 0.5mg capsule), it is a medication used to treat enlarged prostate glands in men. It is not typically used in the treatment of androgenetic alopecia. I would recommend discussing the use of this medication with your doctor to ensure it is being used for an appropriate indication. Regarding the duration of Tugain Foam 5% use, it is not necessarily true that it needs to be used for a lifetime. Once hair growth has been achieved, it may be possible to stop using the medication and maintain the results with other hair care practices. However, in some cases, hair loss may resume once the medication is stopped, so it is best to follow your doctor s advice on the duration of use. As with any medication, Tugain Foam 5% can have side effects. Some of the common side effects include itching, redness, and irritation of the scalp. In rare cases, it can also cause more serious side effects such as low blood pressure and heart palpitations. It is important to follow the instructions for use carefully and report any adverse effects to your doctor immediately. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Priyanka, General & Family Physician
