The Truth About Hair Growth: 4 Scientifically Backed Tips for Thicker Hair

No magic shampoo grows a mane overnight. Four habits that actually maximize hair growth and density.

Let’s bust a myth right out of the gate: no magic shampoo is going to grow you a full mane overnight. However, you can maximize your hair’s growth rate and density by treating your scalp like premium soil.

If you want thicker, healthier hair, start implementing these four habits today:

1. Stimulate the Scalp Daily: Massaging your scalp increases blood flow to your hair follicles, delivering vital oxygen and nutrients. Do this for 4 minutes a day in the shower.

2. Watch Your Protein and Biotin Intake: Hair is made of a protein called keratin. If you aren’t eating enough lean proteins, eggs, and healthy fats, your body will divert nutrients away from your hair to your vital organs.

3. Dial Back the Heat: If you blow-dry your hair on maximum heat every single morning, you are boiling the moisture out of the hair shaft, leading to breakage. Keep it on the cool or medium setting.

4. Keep Your Scalp Clean: Heavy product buildup can clog pores and stifle follicle growth. Wash thoroughly, and consider a clarifying shampoo once a week.
