Frequently Asked Questions
How long does it take to see visible results?
Patience is essential here, as hair grows in slow cycles. Most people start to see noticeable improvements after three to four months of daily use. Do not be discouraged if you see very little change in the first few weeks.
Will my hair fall out more when I first start using a serum?
It might seem counterintuitive, but a temporary shed is actually a common sign that the product is working. The serum is simply pushing out old, dormant hairs to make room for the new, stronger growth underneath. This phase usually stops within a few weeks.
Can I use these serums on color-treated hair?
Most serums are designed to be safe for chemically processed hair. Just be careful to apply the product directly to your scalp skin rather than saturating your colored strands. If you are concerned about fading, look for sulfate-free or specifically color-safe labels on the packaging.
What happens if I stop using the serum?
Hair growth treatments are not a permanent cure for thinning, but rather a maintenance plan. If you stop the application entirely, any newly grown hair will likely return to its previous state within a few months. Consistency is the primary factor in keeping your results.
Can I apply the serum to wet hair?
Most manufacturers recommend applying the product to a dry or towel-dried scalp for the best absorption. If your hair is soaking wet, the water dilutes the serum and makes it run off before it can soak into the follicles. Aim for a clean, damp scalp to ensure the active ingredients can get to work.
