Crinagen was developed by Dr. Nasser Razack after he began experiencing hair loss as a college student in his mid-20s. His realization that few credible treatment options were available at the time led to extensive medical research into its causes and possible treatments on his part. In 1997 he published “Conquering Hair Loss, A Complete Medical Guide To Hair Loss Assessment, Prevention and Restoration”, a comprehensive book that sets out the results of his research in great detail. At the same time, his company Raztec Enterprises launched Crinagen as an all-natural topical spray designed to be applied to the scalp to prevent hair loss and help regrow hair.

Currently an interventional neuroradiologist at Bayfront Medical Center in Florida, Dr. Nasser Razack’s approach to the problem of hair loss has always been meticulously scientific. Crinagen only contains ingredients and compounds that have been medically proven to be effective in treating hair loss, and Dr. Razack’s review of the medical literature is as comprehensive as possible. The basic ingredients of Crinagen have remained the same since it was first produced, although several new versions have been released over time. Each new version introduces minor changes to the product, but Dr. Razack is slow to make changes to Crinagen’s formula because he prefers to wait for conclusive medical evidence before deciding to include a new ingredient. The current version was published in October 2001 and is the fourth to be published.

Because it is a topical and all-natural product like Revivogen, Crinagen can be used by men and women alike and has no systemic or hormonal side effects. In addition to being a DHT inhibitor, Crinagen works to increase blood flow to the scalp follicles. It also suppresses immune system reactions that can cause scalp inflammations which in turn aggravate the damage done to the follicles by DHT. Crinagen has been shown to reduce DHT production in the scalp by up to 98%. Its ingredients not only fight hair loss, but are also combined in a way that allows Crinagen to work simultaneously on several fronts at once. Some of its most potent ingredients are azelaic acid, vitamin B6, zinc acetate, niacin, saw palmetto, ginkgo biloba, and proanthocyanidins from grape seed extract.

Unlike other topical scalp solutions, Crinagen is not sold with associated shampoos and conditioners. Typical of his sound medical methodology, Dr. Razack explains this simply by stating that they are unnecessary as effective options already exist on the market. For use with Crinagen recommends an anti-inflammatory shampoo like Nizoral or T-Gel.

In addition to Crinagen, Raztec Enterprises later developed Natrecia, an herbal supplement specifically blended to combat hair loss. Natrecia can be used by both men and women with minimal side effects and is designed to be taken as a pill once a day.

A 30-day supply (1 bottle) of Crinagen costs $19.95, although it’s worth buying more because the price per bottle is reduced if you buy 2 or 4 bottles at a time. A 30-day supply of Natrecia is also $19.95 and there are similar advantages to buying more bottles at one time. Shipping in the US is free.

Neither Crinagen nor Natrecia are FDA-approved because, like Revivogen, their exclusively natural ingredient lists mean they do not require such regulation. Crinagen was developed before the comparable product Revivogen appeared on the market and although it has many loyal customers, it now exists in the shadow of the latter product in terms of market share. However, this may have more to do with marketing than anything else, as Dr. Razack’s product website has a lot of science and relatively little marketing. In fact, with its triple action approach to inhibiting DHT production, stimulating blood flow to the scalp, and suppressing immune system reactions within the follicles themselves, Crinagen fights hair loss on more levels than its strongest rival. new but more cleverly marketed. However, this may all be about to change, as the Raztec Enterprises website is currently undergoing a facelift for a relaunch in the near future.
