Hair loss treatment company Ashley and Martin has been fined more than $350,000 for unsubstantiated marketing claims about its work.
The company had claimed its treatment, which costs up to $5000, had a 98 percent sucess rate.
But the company had no reasonable basis for its claims.
As a result of the fine, the company has stopped making the claims in advertising material.
Commerce Commission associate commissioner Anna Rawlings spoke to Māni Dunlop.
