Regaine Side Effects

There is always a chance that each and every medication that you use will cause unwanted side effects and Regaine is no different. Most who use this popular hair loss treatment encounter none or only very minor side effects. For more information on the side effects of Regaine please consult the included patient information leaflet or if you have not yet purchased any visit the official website. If you are experiencing any which concern you stop using the medication and consult your doctor.

Here I will outlined all the side effects I’ve discovered through both the official site, hair loss forums and other medical resources online. Please make certain you read these carefully all the information included with your Regaine products before using it for the first time. On a personal note I have used Regaine for many years (8) and haven’t experienced ANY of the effects listed here (this is the case for the majority of users). It’s very probable you won’t experience any either and if you do it is likely that they will stop once you stop applying it.

Common Side Effects


Headaches are listed as the most common side effect (note that it is not common to experience headaches with Regaine – most don’t – it is simply the most reported side effect). If you find yourself experiencing them frequently while using Regaine speak to your doctor.

Scalp itching and dryness

One of the most common side effects associated with using this product, particularly the topical solution, is a flaky, itchy scalp. This is usually caused by one of two things:

  1. Dermatitis
  2. The dried solution itself flaking off.

If it is dermatitis you could try reducing the frequency of application or using a reduced strength solution (2%). Nizoral shampoo can help with the itchiness and flaking but if the problem persists and is that such severity that you cannot live with the irritation it is probably best to stop using Regaine and start looking for a different solution to your hair loss.

As Regaine contains alcohol it’s possible that you might experience dryness and itching of your scalp after application. There are products which can help with this issue such as shampoos. Also if you are using the Topical Solution try the Foam instead. If you experience this effect it may just be a matter of getting used to it or discontinuing its use.

Increased hair loss in the first few weeks

This occurs to many who use Regaine for the first time. A few weeks in and you find that you are losing more hair than when you were not applying it. This is fairly common as many of you hair follicles are entering a shedding phase – they will grow back stronger eventually. If fact this is a good sign that the treatment is have an effect of you follicles and you will very likely be one of those who benefit from using Regaine.

It is not uncommon for hair loss to increase for the first few weeks of use. So if you notice more hair loss than normal don’t worry, this is a good sign that the Regaine is having an effect and that the chance of positive results is increased.

Less Common Side Effects

Faster heartbeat or dizziness

This is rare but obviously serious effect. If you experience it or/and have had previous heart problems consult your doctor immediately. It generally only occurs if Regaine is applied excessively. Please remember to follow the recommend dosage. Applying Regaine in larger does or more frequently then twice a daily will make little if any difference to the recovery of you hair.

Unwanted hair growth

Minoxidil (Regaine) is very powerful stuff for most of us. It’s effects can work on other parts of our bodies (not just the scalp). It will increase hair growth on any part of the skin it come into contact with. When applying the Foam or the Topical Solution the are usually just the scalp and the hand. Always make sure you wash your hands thoroughly after applying.

Serious side-effects

These are very rare but if you notice any you should stop using Regaine and contact your doctor immediately.

  • Chest pain
  • Irregular heartbeat
  • Difficulty breathing
  • Dizziness
  • feeling faint
  • Blurred vision

Other side-effects

It is rare but possible that you may experience

  • Increased growth of facial hair
  • Inflamed scalp
  • Acne at the location at which you apply the Regaine
  • A rash or swelling

Reading a long list of side effects can often be quite worrying but please try and remember with that Regaine just like any other medicine serious side-effects our very rare and really the only side effect that you may experience is an itchy, flaky, dry scalp. This has no health issues and usually comes down to whether you can ease it by using an anti-dandruff shampoo or simply live with it.

The majority of Regaine users experienced no side-effects whatsoever.
