Question 1

What dose should I pick based on my age and hair loss?

Accepted Answer

Your physician makes the final call, but here’s how men usually line up:

0.5mg: the recommended start for most new patients at any age, especially if your loss is mild and the goal is to keep what you have. Men over 30, whose loss tends to move more slowly, often stay here.
1.5mg or 2.5mg: men 18 to 30 with active, progressing loss (around Norwood 2 to 3), or anyone who’s been on 0.5mg and wants more suppression.
2.5mg: men 18 to 25 losing hair at both the crown and the front, men on TRT, and men who want the highest dose that’s been studied.

Question 2

Who decides my dose?

Accepted Answer

A licensed physician through MD Integrations. You can request a dose in your intake, and the physician reviews your age, history, photos and any medications before approving it, or suggesting a different one.

Question 3

Can I start at 2.5mg?

Accepted Answer

Some men do, if the physician agrees it fits, most often for aggressive early loss or TRT. Many start at 0.5mg or 1.5mg and step up after about 90 days. The 2.5mg dose

Question 4

Why would anyone take more than 0.5mg?

Accepted Answer

Because scalp DHT, the number that matters for your hair, keeps falling as the dose rises. In Olsen et al. (J Am Acad Dermatol, 2006), scalp DHT dropped 51% at 0.5mg and 79% at 2.5mg. 1.5mg wasn’t tested in that trial; it sits in between, at an estimated ~65%. The higher-dose evidence

Question 5

Is 2.5mg better than finasteride 5mg?

Accepted Answer

In the same Olsen 2006 trial, dutasteride 2.5mg produced greater hair counts than finasteride 5mg at 12 and 24 weeks, and lowered scalp DHT by 79% versus 41% for finasteride 5mg.

Question 6

Is a higher dose less safe?

Accepted Answer

Higher doses mean more drug exposure, which can change both the potential benefit and the potential risk, and there’s less long-term hair-loss-specific safety data at higher doses. That’s why 1.5mg and 2.5mg require informed consent and physician sign-off. Drug safety

Question 7

How do I increase my dose?

Accepted Answer

Most men step up after a 90-day cycle. You tell your physician how you’re doing, they review it, and if it makes sense your next shipment changes. 1.5mg is 3 softgels a day, and 2.5mg is 5. Increasing your dose
