Regaine Extra Strength for Men

Oral medication

Regaine Extra Strength is a topical treatment for men experiencing male pattern hair loss (androgenetic alopecia), which may affect you if you are genetically susceptible, meaning it runs in the family. Regaine Extra contains the active ingredient minoxidil, at a strength of 5%, and is applied directly to your scalp to stimulate hair re-growth in as little as 8 weeks.

Suitable hair loss treatments

Regaine Extra Strength is a suitable treatment for male pattern baldness if you are male and between the ages of 18 to 65. It is not a cure for hair loss, but it is an effective treatment to stop and reverse hair loss for as long as you continue treatment.

 Nutrition information for medication

You may find losing your hair upsetting, but you are not alone. You may find speaking to other people in the same situation or even counselling helpful. You should also look after your scalp. Don’t forget to use sun protection when the sun is out.

How does Regaine Extra Strength work?

Normal hair growth occurs in cycles, individual hair follicles alternate between resting and growth phases. Higher levels of the hormone dihydrotestosterone (DHT) interrupt the cycle and can result in a reduction in the growth phase and thinning of the hair. Regaine Extra works directly on your scalp, increasing blood circulation to the hair follicles and also stimulating the hair follicles to switch to the growth phase for longer periods.

Is Regaine Extra Strength suitable for me?

If you are experiencing hair loss as ‘male pattern baldness’ then our doctors can help you to decide if it is suitable for you, following a brief online consultation. If you would prefer to use a topical treatment to apply rather than an oral treatment, then Regaine Extra may be more suitable for you.

Get Started

How do I use Regaine Extra Strength?

You should apply Regaine Extra Strength twice daily to the affected areas of your scalp using the included applicators. 6 pumps of the applicators will deliver your total dose of 1ml of Regaine Extra solution, ensure the solution is massaged into your scalp with your fingertips. After application is complete, it is important to wash your hands and other areas of exposed skin where hair growth is not wanted.

Hair does not need to be washed before using Regaine Extra. If it is washed, then your scalp must be thoroughly dry before applying Regaine Extra. After application of Regaine Extra the hair should be allowed to dry naturally without using a hairdryer.

You must then allow 12 hours between applications.

What do we need to know?

Regaine Extra Strength is not a cure for hair loss but it is very effective whilst you continue to use it regularly. Once you stop using Regaine Extra, any results you see will start to reverse again.

Studies have shown the 5% solution produces significantly improved results compared with the 2% solution.
