Rogaine Information on Dosages, Side Effects and More
Here is a compilation of information that may be of interest. We get quite a few inquiries regarding the side effects of Rogaine and Minoxidil. On this page we hope to answer your Rogaine side effect questions as well as clear up some questions about the effectiveness of Rogaine and Minoxidil. We hope this is helpful.
The correct amount of Rogaine or Minoxidil to use is 1 ml. of minoxidil or Rogaine liquid solution or 1/2 capful of Rogaine Foam. This dose is applied to the scalp twice daily. Be sure to keep your scalp dry for at least four hours after application. If your scalp gets wet (such as being caught in the rain), dry your scalp and reapply the solution. Any hair styling products should not be applied until the medication has dried on the scalp.
Using extra Rogaine or Minoxidil has not been shown to improve the effectiveness of Rogaine and Minoxidil solutions. In other words, using more than the suggested amount is just a waste.
Possible Side Effects
Used correctly, the amount of Minoxidil absorbed into the scalp is not enough to cause serious side effects. The most common side effect of Rogaine is itching where the product is applied.
6% of participants in the Rogaine clinical trials experienced itching of the scalp. Many of our customers combat this itching sensation with a dandruff shampoo. We like Head and Shoulders, Nizoral or Neutrogena T-Gel. If you still experience itching in the area where you apply Rogaine, stop using minoxidil, and consult your doctor.
Minoxidil topical solution is the only drug approved by the Food and Drug Administration (FDA) to treat pattern baldness and hair loss. Pregnant or nursing women should not use Minoxidil.
According to clinical studies by Pharmacia & Upjohn, minoxidil yields better results on those who are younger and who have had recent hair loss (less than 10 years). The most treatable bald spots are 4 inches in diameter or smaller, but still with small amounts of fine hair growth.
In a double-blind, peer-reviewed study that involved 300 men over a 48 week period over 44% of the men regrew hair. The men who were most likely to regrow hair:
* Had been experiencing hair loss for less than 10 years.
* Had a balding area that was less than 4 inches across.
* Had more hairs in the center of the balding area.
Patients that use minoxidil have noticed a decrease in hair shedding. Physicians are unsure if the long term positive results of Rogaine are the result of more hairs being grown or fewer hairs lost. What they do agree upon is that Rogaine works best if you still have hair left and is less effective if your baldness is more advanced.
One disadvantage of using minoxidil is that the patient must use it for life or else any regrown hairs will fall out. The FDA points out that only those individuals who experience hair loss on the crown (as opposed to the front of the scalp) will see regrowth.
Male users should detect hair regrowth within eight months, female users within 12 months. Using minoxidil more than twice a day will not make hair grow faster. In addition, it will increase the risk of systemic absorption.
Do not use minoxidil if you have any of these systemic effects: chest pain, rapid heartbeat, faintness, dizziness, sudden unexplained weight gain, or swelling of the extremities. If any of the above symptoms occur, call your doctor. Oral minoxidil is used to treat high blood pressure and is only available by prescription. Topical minoxidil is not absorbed in the same way that oral minoxidil is, however anyone with a heart problem should use topical minoxidil only under the supervision of a physician.
Any breakage of the skin will cause Rogaine and Minoxidil to be absorbed in the system more rapidly. So do not use this product if the scalp is inflamed, infected, painful or irritated. Also scalp abrasions, psoriasis, or even sunburn may increase the absorption. Speak to your doctor is any of these conditions apply. Minoxidil is for use on the scalp only.
Using Minoxidil has not been shown to have any effect on eyebrow, chest, back, beard, or any other hair growth.
