Carolyn Aronson: The Puerto Rican Stylist Who Built a Beauty Empire From One Miracle Bottle
Carolyn Aronson’s rise in the beauty world is anything but ordinary. Long before she became the powerhouse founder and CEO of It’s a 10 Haircare, she was a young girl navigating foster care, adoption, and a search for identity rooted in her Puerto Rican heritage. Her journey from the salon floor to the head of a global brand proves what passion, persistence, and a clear vision can create. Today, she stands as one of the richest Puerto Rican women in the beauty industry, and her empire was built one bottle at a time.
A Childhood Shaped by Resilience
Born Iris Ernesta Reyes to Puerto Rican parents, Aronson entered foster care early in life before being adopted by a family in Michigan. Her upbringing was filled with both tenderness and uncertainty, but it also instilled in her a drive to push forward, learn quickly, and carve out her own destiny. She grew up in the Midwest surrounded by love, yet always aware that her roots stretched far beyond cold winters and quiet suburbs. That connection to her Puerto Rican identity became a meaningful part of her personal story, one she embraced fully as she grew older.
From a young age she gravitated toward beauty and creativity. Hair became her language, a way to express herself and connect with people. While other kids were still figuring out what they wanted to be, Aronson knew she belonged behind a salon chair.
A Stylist Before She Was a CEO
By the time she reached adulthood, Aronson had trained as a professional hairstylist and entered the world of hands-on beauty. Working long salon hours, she witnessed every type of hair challenge imaginable. Frizz, breakage, heat damage, dullness, dryness—she saw it all. More importantly, she learned what clients actually wanted: products that worked instantly, consistently, and without complicated routines.
This real-world knowledge would later become her biggest competitive edge.

A First Business, A First Lesson
Before It’s a 10, Aronson co-founded a smaller brand that ultimately struggled due to manufacturing and distribution issues. It was a setback, but one that sharpened her instincts. The experience taught her the importance of quality control, trustworthy suppliers, and the power of having one perfect hero product rather than launching with a scattered lineup.
Where some entrepreneurs might have quit, Aronson regrouped, learned, and returned stronger.
The Birth of It’s a 10 Haircare
In 2005 she launched It’s a 10 Haircare with one goal in mind, to create a product that could truly do it all. The result was the now-iconic Miracle Leave-In, a multitask formula that detangled, added shine, tamed frizz, protected from heat, softened hair, and more. Instead of expecting women to buy ten different bottles, Aronson created one miracle solution—hence the name.
She started small, partnering with salons and handing out samples. But once stylists tried it, the brand spread on its own. Clients returned asking for the product by name. Shelves began to empty faster than they could be restocked. Word-of-mouth turned a startup into a sensation.

From Salons to the Super Bowl
As demand grew, Aronson expanded distribution carefully, making sure the formulas always remained high quality. The brand broke into major retailers, then went international. By the mid-2010s It’s a 10 had become one of the most recognizable independent haircare lines in the world.
Then came the boldest move of all.
In 2017 It’s a 10 became the first independently owned haircare brand to air a commercial during the Super Bowl. The ad introduced the company to millions of new consumers and cemented Aronson’s place as a major force in beauty.
Growing an Empire While Staying Independent
Unlike many brands that eventually sell to major corporations, Aronson kept her company private and female-owned. Over the years she expanded the line, added new formulas, and eventually launched an entirely new brand, Be a 10, entering the cosmetics market with the same high-performance focus.
Today her products sell worldwide, and her company generates hundreds of millions in annual retail sales. Interviews and industry estimates consistently place Carolyn Aronson among the wealthiest Puerto Rican female entrepreneurs, a title she earned through sheer determination.
The Power of Heritage and Identity
Although she was raised far from where her story began, her Puerto Rican heritage remains a point of pride. Aronson has spoken about reconnecting with her roots and her biological family later in life, a journey that brought her full circle. She often credits her upbringing, her culture, and her early experiences with shaping her resilience and ambition.
Her success is a reminder of how identity, even when complicated, can become a source of strength.

A Legacy Still in Motion
Aronson continues to lead It’s a 10 Haircare with the same stylist-first approach she started with, always asking what real people need and how to deliver results without overcomplicating routines. She is a CEO, a trailblazer, a mother, and a creator with a global footprint, yet she still speaks like a stylist who loves making people feel confident.
And that is exactly why her brand continues to grow. Because behind every bottle, there is her story.
Recap:
- She started as a stylist and salon owner before becoming CEO. She began working as a hairdresser at 18, and by 1998 she’d opened her own salon. Her many years behind the chair shaped the vision for It’s a 10 — she knew first-hand what people wanted from haircare products.
- Her flagship product, “Miracle Leave-In,” remains a global phenomenon. The iconic Miracle Leave-In is the formula she launched It’s a 10 with, and today the brand sells millions of bottles each year worldwide.
- She bought out her business partner and became sole owner in 2017. That move made It’s a 10 one of the only major haircare brands that is fully female- and Hispanic-owned — a rare feat in the beauty industry.
- Her business has grown exponentially under her full ownership. From selling in only a couple of countries, by 2022 It’s a 10 was available in over 70 countries with estimated retail sales of about USD 500 million.
- She’s a mother — and had her youngest child in her 50s. Aronson and her husband, Jeff Aronson, have a blended family. In early 2021 she gave birth to a daughter at age 54.
- She owns (or owned) luxury yachts — and calls them part of the business too. Aronson purchased a 50-meter superyacht named She’s a 10, which she later sold, and moved on to commissioning a larger yacht, She’s a 10 Too — a 54-meter vessel she helped design. The yachts have served both leisure and business purposes (events, gatherings, brand-related social functions).
- She expands beyond haircare — into cosmetics, hair extensions, business acquisitions, aviation and more. Under her leadership, It’s a 10 grew into a broader beauty and lifestyle enterprise: launching cosmetics line, hair-extension products and even acquiring other hair-care brands to expand its portfolio.
- She’s also a philanthropist and activist for community support. Through her company and personal initiatives, Aronson supports causes including disaster relief for Puerto Rico, youth support, diversity in beauty, and more — often using her platform to uplift under–represented communities.
- Her work ethic: she sometimes works at night even as a mom. Aronson has admitted that in the early days she worked nearly “24/7.” Even now, as a mother and CEO, she balances family and business, occasionally working late hours — illustrating her commitment and drive
