Exactly How to Cultivate Longer, Stronger Hair

Hair color fans — particularly bleach enthusiasts — might want to shift their color strategy. "When it comes to growing your hair out, you always want to know how often clients are coloring and what services might be working against them if they're trying to grow length," explains Bodt. "You can have a healthy double process with bleach, but it may take longer to hit those hair goals."

She recommends shifting to a highlight technique for less damage, possibly going longer between coloring services, and using products such as Redken Extreme Bleach Recovery Shampoo, $22.50 and the brand's Redken Extreme Bleach Recovery Lamellar Water, $22.50, a rinse-out treatment, which fills porous hair strands while making hair soft, smooth, and incredibly shiny.
