I'm a Miami-Based Haircare Founder—Here Are My Secrets for Strong, Silky Hair

The Lineup is a monthly series where we’re giving you an inside peek at the beauty lineups of cool fashion people, editors, makeup artists, hairstylists, and estheticians—all the people we trust the most. Get ready for a behind-the-scenes look at all the can’t-live-without products that make their worlds go 'round.
Hair is a very personal thing. It’s a form of self-expression and personal style, and a good hair day can give you a boost when you’re feeling self-conscious. Ever since I was young, I’ve found confidence in my thick, blonde hair, even when I was insecure about my skin. Believe it or not, Dianna Cohen, the founder of clean haircare brand Crown Affair, had this same experience. "I took so much pride in taking care of my hair—it was my armor to my acne,” she recalls. "It was a source of self-assurance and something I’ve cared for daily since I was young.”
Now, Cohen has been working in the beauty and fashion industry for over 10 years, first as an editorial producer at beauty website Into the Gloss. Throughout her career, friends, colleagues, and even strangers have constantly asked her about her haircare routine. (Take one look at her luscious locks and you’ll see why.) And at a time when clean beauty was booming, Cohen noticed there was a major gap in the haircare market. There weren’t any luxurious formulas made with the clean ingredients she needed and the sleek packaging she wanted, so she decided to create them herself. And in 2019, Crown Affair was born, inspiring people around the globe to actually enjoy their haircare routines.
"Our mission is to shift the mindset around how you care for your hair,” Cohen says with a smile. "Wash day isn’t a chore—it’s something you look forward to.” Crown Affair has an array of products to help you achieve any hair goal whether you’re growing your mane long and strong, quenching your bleached locks (ahem, me), taming frizz in a dry climate, or keeping your hair voluminous in a humid environment like Miami, where Cohen lives. What’s her ride-or-die hair product for tropical climates? The Dry Shampoo ($36), which is made with an innovative powder formula. "It smells incredible and leaves my hair silky and refreshed without clogging my hair follicles,” she says. Check out all 20 of her beauty favorites below—they do not disappoint.
Her Coveted Haircare Routine
"Combs No. 001 and No. 002 are hand-carved in Switzerland from 100% plant-based cellulose acetate, a renewable and biodegradable material. The wide-tooth comb is designed to gently work through tangles without causing breakage. Both combs are made to last and are environmentally friendly options for maintaining healthy hair.”
"We created a mineralized, nutrient-rich dry-shampoo powder to target oils, enrich the scalp, and keep your strands not only refreshed but looking fuller and silkier than ever. It gently absorbs oils and enriches the scalp, leaving your hair voluminous, silky soft, and clean-feeling. It adds beautiful texture and blends seamlessly into the scalp.”
Skincare and Makeup Essentials
"The formula is so nice—it’s really hydrating, absorbs so quickly, and doesn’t leave that layer on your skin that so many oils often do. It smells incredible and is really lightweight. It’s one of the only oils that doesn’t break me out. I use this as a base and a prep for my gua sha.”
"The unique shape of this tool allows you to target specific areas of your face, including the forehead, cheeks, and jawline. With regular use, it can help reduce the appearance of fine lines and wrinkles, improve skin tone and texture, and leave you with a healthy, glowing complexion. It’s truly a game changer!”
Self-Care and Wellness Picks
"This lymphatic drainage tool is one of my favorite parts of my post-shower evening ritual. Using a paddle is an efficient way to boost blood circulation and the lymph system by draining and moving toxins out of the body. I’ll use jojoba oil and apply gentle pressure working from the legs upward to the heart.”
