BURBANK, Calif. — Tracee Ellis Ross, an actress on “Black-ish,” executive producer on the spinoff “Mixed-ish” and, as of last month, beauty entrepreneur, wanted to talk about what wellness means to her. “At 18, I woke up like this,” she said. “At 46, I care for it.”

In September , Ms. Ross released a hair care line, Pattern, which features three conditioners for different curl patterns, a cleanser, a serum made with luxurious oils, and hair tools. The line, she said, is “a 20-year dream, 10 years in the making.”

The move seems like a natural extension for Ms. Ross, who often documents her trials and triumphs — frequently on Instagram — with jade rollers and glass blue balls as one way of dealing with, in her words, the “weird anxieties” that can come with getting older.

According to Nielsen, black women make up 85 percent of spending within the ethnic hair care and beauty aids category. Within the entire beauty marketplace, black consumers spend a total of $473 million in a $4.2 billion industry.
