Limp Roots Are My Nemesis—This Is How to Get Long-Lasting Lift Into Flat Hair
As someone with thick, textured hair, I’ve never considered volume to be much of an issue for me. My hair’s natural, rather unruly waves provide plenty of body and movement through the mid-lengths and ends (sometimes too much), and I tend to seek out products that combat frizz and add shine, rather than volumising hair products or hair texturisers.
However, lately I’ve noticed that the longer my hair grows, the flatter it falls at the roots—and during the recent heatwave is leaving my hair distinctly limp at the end of each day. So, while fine hair isn't something I endure, flat hair certainly is. As a result, I’ve made it my mission to combat that frustrating lack of lift by finding out exactly what the best products for flat hair are. After all, as a beauty editor, one of the questions that I’m asked most about when it comes to hair is how to add volume that lasts (volumising sprays do a pretty good job, FYI). Yet good products are surprisingly hard to find, especially if, like me, you hate the feeling of product in your hair. So, I decided to turn to the experts for help on the most effective root-lifters.
Ahead, I share their honest advice on what really works to lift roots and give flat hair some lasting shape, especially on hair like mine that needs volume at the crown, but already has density through the ends. From root-boosting sprays and thickening foams to featherlight mousses and clever texturisers. Consider this your edit of the best insider-approved products and tips to deliver fullness without the heaviness.
Shampoo & ConditionerBefore we get into the styling itself, I was interested to know whether switching out my usual shampoo and conditioner could help add lift to my roots. “They play a key role in managing flat hair,” confirms hairstylist Charley McEwen. “Volumising shampoos help remove excess oil and residue that weigh the hair down, while lightweight conditioners add necessary moisture without heaviness. The right shampoo and conditioner can create a solid foundation by enhancing the hair’s natural texture and body.”
Now that your hair is clean, it’s all about selecting the right styling products for the best root-lifting results. “Long-lasting volume is all about smart layering and prep,” explains celebrity hair stylist and BaByliss ambassador Syd Hayes. “I love using a root volumising spray without the brilliant lift you often get from mousses. But one of my secret weapons for root volume is a Velcro roller—they’re incredibly effective for lifting hair at the crown or fringe area.”
Undeniably, some of the best products for flat hair can be found in the tools department with an abundance of hair dryers, hot brushes and styling tools on the market designed to help. However, if like me, you’re not the best at styling, then McEwen is resolute on one piece of advice: “Don’t overcomplicate things.” Start by rough-drying your hair with your head upside down to “use gravity to your advantage” and then once the hair is about 80 percent dry, it’s time to get focused. “Lift sections at the crown with a brush and direct hair at the roots,” says McEwen. “You don’t need to master the round-brush technique. Just focus on lifting the root and locking it in with a cool shot. Keep it simple and controlled.”
I tested many, many products for flat hair for this piece, putting them through their paces for their ability to inject lightweight volume at the root of the hair without any stickiness or crispiness. Plus, I called on industry experts to get their tried-and-tested recommendations that they swear by for flat hair in their professional kits. Every single product mentioned adds airy light, feels amazing in the hair and keeps hair from falling flat for the whole day.
