What is DHT?

Dihydrotestosterone, or DHT, is a natural but powerful metabolite of the human body and the main cause of hair loss in both men and women. It’s a chemical derivative of testosterone, created when the metabolism of androgen gets involved with an enzyme called 5-alpha-reductase. It’s formed primarily in the prostate gland, testes, adrenal glands and hair follicles and interestingly, though it is important in early stages of development, DHT can have serious negative effects in adult life. However, there are clinically proven medications that work to address the effects of DHT, like hair loss.

The Purpose of DHT

DHT is the main cause of male and female pattern baldness

Researchers have found that during adult life testosterone, rather than its bi-product DHT, is essential for normal sexual behaviour and important in building protein and in metabolic activities, like the production of blood cells, bone formation, carbohydrate metabolism and liver function.

DHT on the other hand is essential in the development of male characteristics (such as facial hair) during puberty, but later in life it only has “a causative role in acne…prostatic hypertrophy [enlargement of the prostate], and androgenetic alopecia.”*

So ironically, while DHT puts hair on the face early in life, for many men it also takes it away from the scalp.

How Does DHT Cause Hair Loss?

Rather than causing the hair to fall out, DHT actually restricts the follicles ability to produce hair growth. Some people aren’t affected by DHT in the scalp but in those who have a genetic tendency to hair loss, the hair follicles are particularly sensitive to the effects of DHT.

When it attaches itself to the receptor cells of genetically predisposed hair follicles, DHT prevents proteins, vitamins and minerals from providing the needed nourishment to sustain life in these follicles and with this, also causes them to shrink. With miniaturisation, the hair is reproduced at a slower rate meaning it either shortens the growing phase or lengthens its resting stage. The result is thinning hair as the hair shaft becomes finer with each new growth cycle and eventually the hairs stop emerging.

How Do You Treat DHT-induced Hair Loss?

While proper nutrition is important in maintaining hair health, it alone will not counter the effects of DHT. There are only two products that have been licensed by the MHRA for the treatment of hair loss, which means they are both safe and effective in stabilising and reversing hair loss.

Without interfering with testosterone levels, clinically proven hair loss treatments intervene in the process by either counteracting the symptoms to increase blood flow to the hair follicle, or by directly inhibiting the production of DHT.

i am 17 yrs old i lost my hair in that age ,please can you tell me how to regrow my hair

Sarah Belgravia

Hello Ibraahim,

It depends on your particular hair loss condition, however, assuming it is male pattern baldness - the most common form of hair loss in men - then male hair loss treatments should help you to regrow your hair, however, they are not recommended for men who are under 18 years old.

Hello I'm 23 and I started losing my hair in the age of 17 and now I have no way please help me because now it started emmbarassing me.please

Sarah Belgravia

Hello Bilal,

The best thing to do is to visit a specialist for a professional diagnosis of your hair loss condition. They can then recommend the most effective treatments for your type and stage of shedding. Assuming this is male pattern hair loss, this is likely to be a combination course of minoxidil and finasteride 1mg. You can call us on 020 7730 6666 or send us a message to book a free hair loss consultation, or if you are not based in London, simply complete our Online Consultation instead.

I have had an underactive thyroid for about 20 years and am presently taking 125mcg thyroxine daily. However, I am presently experiencing severe hair loss, not something a female wants. My doctor doesn't appear to be taking this seriously which concerns me greatly. This is beginning to have a huge effect on my social life as I only go to work and then immediately home as I am so self-conscious of my hair being so very, thin. Can you suggest anything to help? I'm not in the UK, so it's not like I can even book in for a consultation. Thank you

Finasteride and dutasteride cause sexual dysfunction in men..Some people say this. Is this true ?

16th December, 2015 at 4:21 pm

Sarah Belgravia

Hi Tony, Dutasteride is not approved by the MHRA in the UK or FDA in the USA as a hair loss treatment and is not available from Belgravia. With regards finasteride 1mg you can find out more about the potential side effects here and learn what experts experiences are of this daily tablet here.

11th January, 2016 at 4:49 pm

Sarah Belgravia

Hi Saif, Regaine is a brand of minoxidil used to treat male pattern baldness. Any genetic hair loss treatment will need to be used on an on-going basis in order for it to work effectively. If you stop using your treatment there is nothing to help prevent your hair loss condition - which is permanent and progressive - from continuing.

Stigma

I'm a 19 years old girl.I've been losing my hair 3 years ago doctors said it's genetic, I've been using minoxidil for 2 months and half now with folicum ( vitamins I guess) and no obvious results. Is it normal? I'm afraid I would never get my hair back, is it possible?

Hi Stigma, This does not sound like anything to worry about - to find out more please see here for a full response to your query.

Hi. Im 35 and my hair is thinning by the day. My father and both my grandparents had hair so its not genetics. I have a lot of dandruff and i have been under a lot of stress for years now. Hair have started turning grey considerably very quickly over these 8 months. Can stress be a cause of thinning hair or hair loss ? PS I cannot place an appointment as i live in another country. Ive heard "jamaican black castor oil" is good. Please help. With thanks, Kurt

Sarah Belgravia

Hi Muhammad, Following a healthy diet will help to improve the condition - that is to say the health - of your hair, but it is unlikely to help a hair loss condition. Find out more in this full response one of our senior hair loss specialists has provided.

Beola

Hi, My son is 5yrs old and he started loosing his hair when he was 4yrs. I was made to understand that it is alopecia areata. WHat do you recommend we do? Any lotion or drug he can take? His friends are beginning to make jest of him. Concerned....

18th March, 2016 at 10:55 am

Sarah Belgravia

Hi Beola, We are sorry to hear that. As your son is so young it is best for you to visit your GP in order to get a medical assessment of his condition. Unfortunately we are unable to treat children under 16 years of age as there are age restrictions in place for the medication used in Alopecia Areata treatment (high strength minoxidil). Your doctor will be able to give you practical advice and you could also contact Alopecia UK and the Little Princess Trust who are charities that help girls and boys with hair loss.
