Frequently Asked Questions
Can I apply hair growth serum to wet hair?
Most experts recommend applying serum to a clean, dry scalp for the best absorption. If your hair is soaking wet, the product will likely dilute and drip down your face, which is messy and ineffective.
Will these serums make my hair greasy?
Quality serums designed for growth are typically thin and fast-absorbing. If you notice a greasy residue, you are likely using too much product or choosing a formula too heavy for your hair type.
Do I need to wash my hair every day if I use serum?
You do not need to wash your hair daily, but your scalp should be relatively clean when you apply the serum. If you go several days between washes, dry shampoo or product buildup can prevent the serum from reaching your follicles.
What happens if I stop using the serum?
Hair growth cycles are continuous, so if you stop using a treatment, your hair will eventually revert to its previous growth pattern. Any new growth you gained may gradually shed over several months as the follicles lose that extra stimulation.
Are there side effects I should watch for?
Most people tolerate these serums well, but some may experience mild scalp irritation or dryness. If you have sensitive skin, perform a patch test on your inner arm before applying a new product all over your head.
