What is a scalp serum?

A scalp serum is a specialized hair growth product with a liquid formula designed to nourish the scalp and promote healthier hair growth. These serums often contain vitamins, minerals, and essential oils that target the root of hair issues, improving scalp health and boosting hair strength. Think of it like a vitamin boost for your scalp—just as your body needs nutrients to thrive, so does your hair.

Regular scalp serum can help reduce dandruff, soothe irritation, and create an optimal environment for hair regrowth. 

It's easy to incorporate into your routine; simply apply it to your scalp after washing your hair and massage it to ensure good absorption. Over time, you'll likely notice your hair looking fuller, shinier, and healthier.
