Minoxidil Side Effects – Q&A Guide
Minoxidil is a widely used and clinically proven treatment for hair loss. Like any treatment, some users may experience side effects. Below we address the most common concerns and how to manage them.
Q1. What are the most common side effects of Minoxidil?
The most frequently reported side effects are:
-
Scalp irritation (itchiness, dryness, redness, or flaking).
This is common in the cold winter months, how to counter this: apply another hair care product after minoxidil has dried (this will give it time to penetrate your skin before applying another product) example: Use a leave in hair conditioner or other moisterizers like hair oils. If irritation continues stop using minoxidil and ask us for assistance and guidance
These effects are generally mild and often resolve when using our advise
Q2. I am getting a rash when using minoxidil solution
This is often caused by propylene glycol - a common ingredient found in traditional solution type minoxidil. Some people are sensitive to it.
How to deal with it:
-
allow skin to recover for a few days or a week and switch to a foam version of Minoxidil (our foam does not contain propylene glycol).
-
Use a mild, sulphate free (obtained at pharmacy) shampoo to keep your scalp balanced.
If you still experience a rash from using a propelyne glycol free products it may point to actual minoxidil allergy, stop using and consult with us.
Q3. I noticed increased hair shedding after starting Minoxidil. Should I stop?
No. Shedding can be normal process in a small percentage who are starting Minoxidil. It happens because old, weak hairs are being pushed out to make way for stronger, healthier hairs.
How to deal with it:
-
Continue using Minoxidil consistently. - DO NOT USE MORE THAN ADVISED: USING MORE EG: MORE THAN 1ML PER APPLICATION CAN LEAD TO MORE HAIR SHEDDING
-
Shedding usually stops within 2–3 weeks.
-
If shedding persists beyond 3 weeks, consult us for further assistance
Q4. Can Minoxidil cause unwanted hair growth on the face or body?
Yes, some are very sensitive and can be prone to this
How to deal with it:
- If you are a woman and experience unwanted facial hair, use a 2% instead of a 5%. If a 2% still results in facial hair, use the 2% once a day and not twice a day.
- Wash hands after applying the minoxidil as to not affect other parts of your body
Q5. What if I experience dizziness, chest pain, or rapid heartbeat?
These are rare but serious side effects!! please take the following advise seriously

Hair regrowth achieved from Minoxidil will gradually be lost over a few months. Side effects usually disappear quickly (within days) once treatment is stopped.
Q9. Can Minoxidil be used with a derma roller or microneedling?
Yes, but some users may experience increased irritation when combining the two.

Start with once-a-week microneedling before increasing frequency.

-
Apply only to the scalp.

Choose the formulation (foam or solution) best suited to your scalp sensitivity.
