1. Eat Healthy
“Nutrition is the number-one thing that affects hair growth,” says Gregorio Ruggeri, co-owner of Salon Ruggeri in NYC. Ensuring that you’re getting the proper nutrients internally can make a big difference externally, namely in how your hair looks and grows.
2. Adjust Your Styling Habits
Sure, hot tools can give you the exact style you want, but heat is a major cause of hair damage, leading to potential breakage and stunted growth, says Ruggeri.
3. Avoid a Situation On Your Scalp
Healthy hair can only come from a healthy scalp. “You need to keep the follicles clear and healthy in order to ensure healthy hair growth,” says Ruggeri.
What to do: He suggests using an exfoliating scalp scrub weekly to remove product residue and excess oil, creating an environment optimal for hair growth. He likes the Christophe Robin Cleansing Purifying Scrub with Sea Salt ($52; sephora.com). (Or, try a pre-shampoo clay hair mask to absorb excess oil at your roots.)
4. Color Less Frequently
What to do: “If you’re trying to grow out your hair, consider going as long as possible in between coloring, ideally every 12 weeks,” says Ruggeri. And ask your colorist about incorporating a treatment along with your color, like Olaplex, which can help minimize the damaging effects.
5. Change Your Brushing Technique
Brush the right way and you can actually encourage healthy hair growth. Brush the wrong way, and it can have the opposite effect.
What to do: First, pick the right brush. Ruggeri likes cushion brushes with boar bristles, which are gentler on both scalp and hair than their plastic or nylon counterparts
