FAQ Section

How long does it take to see results from these methods?

Most treatments (like minoxidil or diet changes) take 3-6 months to show visible results. Hair grows slowly—about ½ inches per month. Consistency is key!

Can hair grow back if I’m already bald?

If the follicles are completely dead (smooth, shiny scalp), regrowth is unlikely. But if you still see fine hairs, minoxidil and micro needling can revive them.

Is finasteride safe? Will it lower my sex drive?

Finasteride is safe for most men, but 2 3% report side effects like low libido. These usually fade after stopping. Always consult a doctor first.

Which is better: minoxidil or rosemary oil?

Minoxidil works faster (proven by 40+ years of studies), but rosemary oil is natural and helps if used daily for 6+ months. Try both for best results!

Do laser caps work?

Yes! FDA-cleared laser caps (like iRestore) boost hair growth in 85% of users. Use 3x/week for at least 4 months.

Will washing my hair daily make it fall out more?

No—but use a gentle, sulfate-free shampoo. Over-washing can dry your scalp, though. 2-3 times a week is ideal.

Can stress cause permanent hair loss?

Stress triggers temporary shedding (telogen effluvium). Hair usually grows back within 6 months once stress is managed.

Are hair transplants worth the cost?

For advanced balding (Norwood 3+), yes! FUE transplants look natural and last a lifetime. Prices start at $4,000.

What’s the #1 mistake people make with hair regrowth?

Giving up too soon! Most quit minoxidil/diet changes before 3 months—right when results start. Patience wins.

Can I regrow hair without any products?

Yes! Scalp massages + a protein-rich diet, + stress control can help, but results are slower. Combine with treatments for best outcomes.
