Our first commercially available product helps regrow hair by blocking DHT with ostrich antibodies.


It's hard to believe that at my age of 70 I saw hair growth in the front and top of my scalp after approximately 10 weeks. Though never completely bald my hair was so thin that you could easily see my scalp. Now the new hair covers nicely. I am very happy with the results.



I achieved great results within 2 months. I have been using the product for over two years. I just spray it on one or two times a week now to maintain the hair growth. It is so easy to use, and there have been no side effects.



By the 3rd month of use my hair was much thicker especially in the hairline which had thinned considerably. I still use the spray at night and wash it off when I shower in the morning. Great stuff with great results!


Powered by Ostrich Antibodies

The application of ostrich antibodies to human health and well-being is based on the work of Dr. Yasuhiro Tsukamoto. He is the President of Kyoto Prefectural University in Japan, and most recently served as the Dean of the Graduate School of Life and Environmental Sciences. Over the past 20 years, Dr. Tsukamoto and his team have focused on the development of antibodies from ostrich eggs against various pathogens, allergens, other substances. An example is OstriGen’s new product, OstriGrow, which employs a combination of four antibodies to combat male and female pattern baldness.

Why Ostriches?

Over its 23 million years as a species, the ostrich has developed the most powerful immune system on the planet. Ostriches react to a wider range of antigens and produce a meaningful level of antibodies (IgY) in their blood within two weeks of antigen immunization. Within 4 to 6 weeks of immunization, the IgY appears the yolk of their eggs. A hen ostrich will produce up to 4 grams of IgY per egg, so over her 55-year productive lifetime, she will produce an average of 22 kilograms of antibodies.

Another important property of ostrich IgY is that it is essentially impervious to digestive acids and enzymes, opening up exciting possibilities for these antibodies to be used orally in food supplements and in treatment of enteric disease.

Note: Dr. Yasuhiro Tsukamoto is President of Kyoto Prefectural University in Japan, and most recently served as the Dean of the Graduate School of Life and Environmental Sciences. OstriGen is committed to teaming with physicians and scientists that have the greatest knowledge of the pathology of these diseases.

Scientifically Proven Results

Results from our latest study showed that after applying OstriGrow for three months men saw hair count increase 69% and women experienced a 73% increase in hair count.

Natural, with No Side Effects

Unlike other hair growth products, OstriGen has no chemicals, so has no nasty side effects. Just spray it onto your scalp once a day and leave it on at least 10 minutes. It's safe, easy and effective.

Treats Men & Women

OstriGrow is effective at treating both male and female pattern baldness. Many people see hair growth in as little as three months of daily use! Note: OstriGrow only helps people suffering from AGA.

The  Ostrigen Story

Since he was a child, Yasuhiro Tsukamoto had wanted to do research on dinosaurs and birds. Ostriches, he determined, were the best middle ground as they have fingers and nails on the inside of their feathers, which makes them very primitive and near dinosaurs.

As a dean in veterinary science at Japan’s Kyoto Prefecture University, Dr Tsukamoto was able to explore the ostriches' abilities to fight human afflictions. Dr. Tsukamoto was originally tasked to study ostriches for a project in which the birds were fed surplus soy beans, creating fertilizer for local farms. In the early 1990s  he noticed his charges were surprisingly disease-free compared to other captive species. This high level of immunity, he and his colleagues soon gathered, could be traced back to the ostrich's hefty five-pound eggs.

Tsukatomo had an idea: What if he could cus­tomize the antibodies in an unfertilized Ostrich egg and extract them to make various medicines for humans? That question led to his research over the next decade.
