20 Best Serum For Hair Growth And Thickness (2023 Updated)

Serum is a type of hair product that helps to promote hair growth and thickness. Serums typically contain nutrients and other ingredients that are known to support hair health, such as biotin, keratin, and vitamins.

Conclusion

After extensive research, we have concluded that serum can indeed help hair to grow thicker and fuller. However, the results are not always guaranteed and vary from person to person. Additionally, it is important to use a quality serum product that is designed specifically for hair growth and thickness.
