Frequently Asked Questions
How long does it usually take to see actual growth?
Patience is your best friend here. Most people see visible improvements in three to six months because hair follows a natural cycle of shedding and regrowth.
Can I use these serums on braids or protective styles?
Yes, you absolutely should. Using a dropper to reach your scalp between braids keeps the skin hydrated and healthy while your hair is tucked away.
Will these serums make my hair look oily?
It depends on the base of the product. Look for lightweight botanical oils like jojoba or argan if you want to avoid a heavy, greasy appearance.
Should I apply the serum to wet or dry hair?
Most serums work best on a clean, damp scalp because the pores are more open. However, always check the label, as some specific formulas prefer a completely dry application to penetrate properly.
Are these serums safe to use with heat styling?
You need to be careful here. Avoid applying heavy oil-based serums right before using a flat iron, as the intense heat could fry your hair strands. Apply your heat protectant first, and save the growth serum for your nighttime routine.
