What are the most common causes of hair loss?
The most common cause in both men and women is androgenetic alopecia (pattern hair loss), driven by genetics and hormonal factors. Other common causes include alopecia areata (an autoimmune condition), telogen effluvium (triggered by illness, stress, or nutritional deficiency), scalp infections, and certain medications. An accurate diagnosis determines which treatment is most likely to help.
-
Is hair loss permanent?
This depends on the cause. Pattern hair loss is progressive but can be slowed or partially reversed with treatment. Alopecia areata often regrows spontaneously or with treatment. Telogen effluvium typically resolves once the trigger is addressed. Scarring alopecias can cause permanent loss in areas of established scarring, making early diagnosis and treatment particularly important.
-
What blood tests are needed?
Depending on your presentation, blood tests may include full blood count, thyroid function, ferritin (iron stores), vitamin D, zinc, and hormone levels. These help identify systemic causes such as thyroid disease, iron deficiency, or hormonal imbalance that may be contributing to or causing hair shedding.
-
What is the most effective treatment for hair loss?
There is no single answer — effectiveness depends on the underlying cause. Minoxidil and finasteride are well-evidenced for androgenetic alopecia. Steroid injections work well for alopecia areata. Treating an underlying nutritional deficiency or medical condition often leads to significant regrowth. Your dermatologist will recommend the most appropriate approach for your specific diagnosis.
-
How long before I see results from treatment?
Most treatments take 3–6 months before meaningful improvement in hair density is visible. It is important to persist with treatment during this period and attend follow-up appointments for monitoring and reassessment.

Is hair transplant an option?
Hair transplant surgery can be an effective option for appropriate candidates with stable pattern hair loss. At Swift Access Health, we provide thorough pre-transplant assessment and can advise on suitability and appropriate referral pathways where indicated.
Your Patient Journey
1. Your
Consultation
Your dermatologist will take a detailed history of your hair loss — when it began, rate of progression, family history, any associated symptoms, and relevant medical history. The scalp is examined using a dermatoscope (trichoscopy), and blood tests or scalp biopsy may be arranged. A diagnosis is reached and a treatment plan agreed.
