Some natural shampoos have been found to contain chemicals, called essential oils, that have led to breast growth in men and boys. Males who do not desire to grow a pair of "man boobs" should be cautioned against using products that contain lavender oil and tea tree oil. The condition, called gynecomastia, is rare but the chances increase if the above listed products are used.
As more men, however, are deciding to get back to nature and are using products that contain these oils, precautions should be taken. Before starting a health regimen of these products, men should be cautioned to purchase a training bra to get used to wearing one.
To help with this new niche market, Bali has announced that they will begin producing a line of brassieres just for men. They will not be lacey like women's underclothing, but will be designed with the man in mind. They anticipate that the most popular style will be denim, so are manufacturing a greater number of these in anticipation of the growth in men's bras. Other fabrics will include corduroy and plain white cotton.
Bali has not said whether or not they would make men's nursing bras and does not currently have a men's teddy in the works.
