When Heidi Imhof started losing her hair at 42, she also started losing sleep. Ms. Imhof, a lawyer, was afraid that blow-drying her straight dark hair would hasten the shedding, so she got up two hours early to shower and apply mousse and volumizers. When her hair finally air-dried, she’d pull it back, hoping to hide the bald patches on her scalp.
“I was desperate,” she said.
The hair thickening shampoo Nioxin didn’t help. Neither did Rogaine. Then she heard about Harklinikken, a Danish company offering a customized hair extract that’s given only to those who pass a fairly rigorous selection process.
Ms. Imhof, who lives in Land O’Lakes, Fla., was skeptical. The company’s before and after photos seemed too good to be true. But she went for a consultation and made the cut. (Harklinikken’s products are not available to anyone with autoimmune illnesses like alopecia or baldness from scarring, or anyone who is unlikely to see at least a 30 percent increase in growth.)
After three months of applying the $88-a-month serum, Ms. Imhof was so excited by the results that she overcame her embarrassment about the subject and posted her own before-and-after photos on Facebook.
“You can’t see holes in my hair anymore,” she said.
Harklinikken (“hair clinic” in Danish) inspires great loyalty. Four out of five users come as referrals from satisfied customers, said Lars Skjoth, the company’s founder and chief scientist. The results are certainly compelling. After four months of daily application — that is, working the tea-colored tonic into the hair section by section, then letting it sit on the scalp for six hours — most users regain at least 30 percent of lost density, and some as much as 60 percent, according to company figures.
