Most beneficial stages of hair loss to use the Hair Growth Spray
When the spray is started early enough in the hair loss process and is used continually, hair thinning/excess hair loss can be prevented. The treatment works best at the mild-to moderate stages of hair loss: stages 2-5 of the Hamilton-Norwood scale (see illustration below).

Stages of hair loss information
- No notable hair loss or recession of the hairline.
- Often referred to as the 'adult' or 'mature' hairline: some recession at the temples and some sparsity at the front-centre.
- Two variants:
- Either development of deeper recession at the temples with increased sparsity at the front-centre.
- Or recession at the temples and front-centre remains at stage 2, but there is notable hair loss/sparsity at the crown (vertex).
- Recession at the temples and front-centre is developed beyond that of stage 2 and there is hair loss/sparsity at the crown.
- Recession at the temples and front-centre hairlines is developed beyond stage 4 along with increased hair loss/sparsity at the crown. The band of hair between these areas is still present but sparse.
- The areas of hair loss at the front, temples, and crown have extended and merged: the band of hair crossing the crown is lost, with only sparse hair remaining.
- The remaining hair is an (often sparse) band around the back of the head connecting the remaining hair at the sides.
When can I expect to see results?
Hair on the scalp grows at approximately 1cm per month. Thicker, longer, hair with greater scalp coverage, may be seen as early as 3 months with daily use. Excess hair loss has usually stopped after 6 months of daily use and changes are more obvious, with maximum benefit by 1-2 years.
In the unlikely event your hair loss continues beyond 12 months treatment, with no notable increase in hair thickness or coverage, you are likely to be a non-responder and it is unlikely you will benefit from continuing treatment.
Once improved hair coverage has been achieved, continued treatment is required to maintain the benefits. If treatment is stopped, pre-treatment appearance will likely return within 3 to 6 months.
How Dr Fox Hair Growth Spray works
In the average adult male approximately 10% of the male sex hormone testosterone is converted to the more potent hormone Dihydrotestosterone (DHT). DHT is responsible for adult male characteristics including male hair thinning and hair loss. DHT affects hair follicles in a way that prevents hairs from reaching their full growth potential.
For more information see Dihydrotestosterone (Society for Endocrinology).
The active ingredients in the Dr Fox Hair Growth Spray work to reverse hair thinning and hair loss using a combination of the following treatments:
Finasteride
Finasteride reduces the conversion of testosterone to DHT, therefore less DHT reaches hair follicles and hair is allowed to reach its full growth potential.
For more information see Common questions about finasteride (NHS).
Finasteride can be taken in tablet form (orally), but more recently treatments applied directly to the scalp (topical) have had promising results in clinical trials.
A significant benefit of topical compared with oral treatment, is the reduced risk of side effects (e.g. sexual dysfunction). Topical finasteride is not yet licensed to treat male pattern hair growth, but is a safe and effective alternative to oral treatment and is available on private prescription.
Minoxidil
Minoxidil relaxes small blood vessels where it is applied to the scalp, increasing blood flow to hair follicles. Blood carries essential oxygen and nutrients which stimulate new hair growth, encouraging thicker, longer, more visible hair. Minoxidil has been proven to stimulate hair regrowth, likely by enhancing cell multiplication.
Topical minoxidil is already licensed to treat male pattern hair loss (e.g. as Regaine).
Tretinoin
Tretinoin is a vitamin-A derivative that promotes hair growth indirectly by increasing minoxidil uptake. Minoxidil spray alone is best used twice daily, but combined with tretinoin allows minoxidil to be used once daily with equivalent results in clinical trials.
DO NOT use Dr Fox Hair Growth Spray if you:
- Have an allergy or hypersensitivity to finasteride, minoxidil, or tretinoin.
- Are susceptible to severe scalp infections or psoriasis.
- May have hair loss due to a cause other than hereditary 'pattern' hair loss, e.g. chemotherapy, total alopecia (hair loss over the entire body). If you are unsure you should consult your GP.
- Were assigned female at birth.
Cautions for use of Dr Fox Hair Growth Spray
- Keep away from children and animals. If swallowed, minoxidil can lead to heart toxicity.
- Pregnant women and women with childbearing potential should avoid using or handling as finasteride may affect development of a baby's genitals.
- Avoid exposure to UV light (sunlight) as tretinoin can make the skin more likely to burn.
- If treatment is stopped the beneficial effects will likely reverse within 6 months.
Consult your GP before using if you:
- Have heart disease, treated or untreated high or low blood pressure (cautions for minoxidil 5%).
- Have a history of urinary obstruction, or difficulty passing urine, this may be caused by an enlarged prostate gland (caution for finasteride).
- Develop male breast changes - lumps, pain, enlargement or nipple discharge, as these may indicate underlying breast cancer (caution for finasteride).
- Develop male breast tissue growth (gynecomastia). This is an uncommon side effect of finasteride (usually in higher doses in tablet form) and early management increases the likelihood of complete reversal.
- Have a PSA (prostate specific antigen) blood test. Topical finasteride may alter the test results.
Possible side effects of Dr Fox Hair Growth Spray
Side effects are much less likely when using topical rather than tablet form (oral) medication as active ingredients are delivered directly to the skin with little entering into the bloodstream.
Dr Fox advises you stop treatment if any of the following symptoms develop and see your GP if they do not resolve:
- Skin irritation (itching, dryness, redness) at the application site is most likely due to the alcohol base, but may be due to minoxidil or tretinoin. Irritation usually settles with continued use.
Uncommon side effects
- Symptoms of low blood pressure/lightheadedness.
- Male breast tissue growth (gynecomastia).
- Low mood/depression.
- Allergic reaction: itchy, red scalp, swelling of the lips, face, tongue, or throat; breathing difficulties or difficulty swallowing.
For the full list of potential side effects read the ">Patient Information Leaflet (PIL
Reporting side effects
Worrying or unwanted side effects should be reported via the MHRA Yellow Card scheme, also available via their app which can be downloaded from Apple App Store or Google Play Store.

Alternative hair loss treatments
Oral finasteride 1mg tablets and minoxidil only topical applications are also available from Dr Fox. These should not be used at the same time as the Dr Fox Hair Growth Spray.

Patient Information Leaflet

The Patient Information Leaflet (PIL) is the leaflet that accompanies the medicine pack with a medicine and must be read before taking the medicine. It is written for patients and gives information about taking or using a medicine.
The hair growth cycle
Hair growth is a continuous process which can be explained via 4 cycling phases:

- Anagen (growth) - a single shaft of hair grows from a hair follicle for 2-8 years. Hair length depends upon the length of this phase (unless the hair is cut).
- Catagen (regression) - over 1-2 weeks, the supporting hair follicle regresess and detaches from the hair. The hair however remains in place, secured by a small white bulb of keratin.
- Telogen (resting) - the old hair rests for 2-3 months. while the old hair is resting, a new hair develops at the base of the hair follicle (the start of anagen for the new hair).
- Exogen/Anogen restart (shedding) - as the new hair grows, it pushes the old hair out. On the diagram above, exogen occurs between anagen restart and anagen.
For individuals not experiencing hair loss, it is normal to shed over 100 scalp hairs per day!
- If the anagen/growth phase moves into the catagen/regression phase prematurely, excess hair shedding and thinning occurs. This is characteristic of male pattern hair loss.
- If the percentage of hair follicles remaining in the telogen/resting phase is increased, hair loss decreases.
Dr Fox Hair Growth Spray FAQs
Why should I choose Dr Fox Dual Action Hair Growth Spray?
Dr Fox hair growth spray contains both finasteride and minoxidil, with tretinoin to boost their effects and allow once daily use. It is a great option if you experience side effects when taking oral finasteride 1mg/Propecia as the main action of the spray is at the level of the scalp therefore the side-effects of finasteride are reduced.
Can I use the Hair Growth Spray at the same time as finasteride tablets?
No. The Dr Fox Hair Growth Spray contains both finasteride or minoxidil and should not be used on the same day as other finasteride or minoxidil containing medicines. If you would like to try the spray alongside finasteride tablets you could alternate treatments, using them on different days.
Is Dr Fox Hair Growth Spray licensed to treat male hair loss?
Dr Fox Hair Growth Spray is manufactured as a 'specials' medicine by a licensed UK medicine manufacturer, Xeal Pharma (MS 46688).
Specials medicines are not required to go through the medicines licensing process.
Dr Fox Hair Growth Spray is supplied on prescription only and patients must consent to being supplied with an unlicensed medicine during the consultation and ordering process.
The active ingredients in the spray have been proven to treat male pattern hair loss.
Can finasteride cause sexual problems?
There is much controversy online about this subject that is associated with oral tablets. The manufacturer's finasteride 1mg tablet patient information leaflet provides details and the NHS reviewed a study regarding these concerns in 2017 and concluded that stopping the tablets would resolve sexual problems in nearly all cases. See also the mystery of post-finasteride syndrome.
As a topical application, the Dr Fox Hair Growth Spray is applied to the scalp only, and only small amounts of the active ingredients will pass into the blood stream.
