I'm 23 years old, and about 2 years ago, I used minoxidil 5% for my hair loss. After 4 months, I saw good results with hair growth, but then about 2 months later, my hair started falling out again, so I stopped using it. Now, after 2 years, I'm thinking of using minoxidil 5% again. Is it safe to restart it now, and should I expect the same results?

It's okay to try minoxidil again after two years, but be prepared for shedding initially, as it can happen when restarting. Continue using it consistently for at least 4-6 months to see results. If you notice any irritation or side effects, consult with a dermatologist. Remember, minoxidil works best with long-term use.
