Hair loss causes

Hair loss causes

The most common hair loss causes are genetic and hormonal, followed by illness and trauma. Causes of male and female hair loss will be considered separately.

The average lifespan of a single scalp hair is 3 -7 years, the hair then falls out and is replaced in three months by a new hair. The cause of hair loss can be due to the hair falling out faster than usual (shedding), regrowing back poorly or not growing back at all. In addition, the quality of the skin can be the cause, rather than the hair itself. There are a number of conditions and situations that cause hair loss which effect both men and women these are discussed below. As we mentioned earlier it is important to understand the cause of your hairloss and then you will be able to find the most appropriate treatment. The list of hairloss causes below can affect men or women.

Other Hair Loss Causes – Alopecias

Strictly speaking alopecia simply means hair loss but doesn’t explain what the cause actually is. For example:

Alopecia areata

is a common cause of hairloss, more so in women and gives a patchy type of hair loss, which spontaneously improves, usually after a few months.

Androgenic alopecia

Androgenic alopecia is in fact male pattern hair loss and not to be confused with these other types.

Traction Alopecia

Traction Alopecia is where the cause of the hair loss is damage to the hair follicle by pulling on the root or bulb of the hair – effectively plucking it out slowly. Often this damages the hair so much it doesn’t grow back or only weakly.

Examples include Afro braiding, Sikh twisting the hair under the turban and simple but very tight pony tails.

Eyebrows and Eyelashes

Eyebrow hair transplants can be very successful in cases where hair has been lost due to excessive plucking, trauma or congenital lack of eyebrows.

Eyelash damage is also often caused by trichillomania and eyelash extensions, where the glue just rips out the eyelash as the extension is removed.

Burns cause hair loss by physically heating and killing the hair follicle and surrounding skin cells. Superficial burns may cause the hair to be burnt off (flash burns) leaving the deeper skin and hair bulb undamaged (and will regrow) or the burn may be deep and causing contracted scars with no hair growth.

This is a wide ranging category, as many medications can cause changes in hair quality or hair loss. Usually, these side effects are uncommon but do occur and there is some overlap with the Hormonal category below i.e. Oral contraceptive pill.

There is often a characteristic loss of sideburn hair in front of the ears when patients have facelifts performed, although there are now newer techniques to avoid this.

Although typically hormones cause hair loss most commonly in women, there are some hormonal changes that affect men equally.

Radiation Therapy Hair Loss

This hair loss cause is quite similar to a burn in some respects. Essentially, the skin is damaged by the radiotherapy treatment but usually recovers. However, hair is very sensitive to the radiation and is killed by it.

If caused by trauma, then the hair loss cause situation is again very similar to burns, above. Old fashioned hair punchgrafts and scars from other previous hair surgery, can be improved in a number of ways: Rows of punchgraft “dice” scars can be removed simply by excision, usually with immediate improvement.

Tricillomania is a similar cause to excessive plucking of eyebrows. Obsessive pulling or twisting of scalp hair causes damage to the hair root until it no longer grows properly. Once the patient has stopped the Obsessive Compulsive behaviour ( OCD ), then the damaged hair can be replaced by hair transplant surgery.


There are some diseases that cause hair loss that are not treatable using hair restoration techniques. Please contact us if your condition is not covered by this information and you require further advice.

Dr Rogers Compliment Letter 2015 – SG

When I arrived at the clinic on Harley Street I was welcomed warmly by the staff and did not have to wait long before the Surgeon (Dr Richard Rogers) came and introduced himself. I then sat down with Dr Rogers who spent time getting to know me, asking very detailed questions. He then spent some time with me penciling on different hairlines giving me plenty of time to think, whilst giving his expert opinion and advice on what would look the most realistic. When I had decided on the placement of my new hair line Dr Rogers made sure that I was happy with the outline drawn one last time walking round showing me it from different angles using a mirror. Through Dr Rogers being so intent on making sure I was 100% happy with the procedure before going ahead really helped me feel comfortable and sure with my decision. With my hairline drawn and having been made to feel completely relaxed by Dr Rogers I was walked to the surgery. Even then Dr Rogers continued to make me feel comfortable introducing me to each of his nurses and explaining each step to me in detail of what they would be doing whilst he performed the procedure.


Having talked through the procedure with me and going over everything in extreme detail Dr Rogers asked me to place myself on the chair and then began to adjust the position making sure that I was completely comfortable. Now that I was sat comfortably and ready for the procedure to begin Dr Rogers began to guide me through each step before doing so. To begin with he explained that he would be administering general anesthetic to numb the surrounding area, and told me that it may hurt a little like a pinch. However, I did not feel a thing! In fact I didn’t even realise Dr Rogers had begun, he was so gentle and light handed I was shocked and of course extremely pleased! With the first part out of the way and the surrounding area completely numb, Dr Rogers told me that he would now begin to remove the strip of skin. At this stage I could honestly not believe how it was possible that I could not feel my skin being cut away. Throughout the procedure I was not once in pain and Dr Rogers continually made sure that I was ok and checked that I was in no kind of pain.


Better still Dr Rogers talked to me throughout the procedure and joined in with conversations between the nurses and myself. This really made me feel at ease and at times I nearly forgot that I was having a hair transplant. With my strip of skin removed and the nurses now taking each hair follicle from the skin, Dr Rogers began to stitch my skin back together. Even now I could not feel a thing and before I knew it Dr Rogers had finished. Whilst the nurses continued to separate the hair follicles Dr Rogers offered me some water and asked if I had any food to eat to help boost my sugar levels. Once I had eaten a snack and topped myself up with water Dr Rogers made sure that I was comfortable before the procedure continued. He then explained that he would be administering some local anesthetic to the surrounding area for the hair follicles to be placed. With the area numbed and having been told what was to happen next Dr Rogers began to make tiny pin pricks into my skin for the hair follicles to be placed in by his nurses. I cannot stress enough how I did not feel a thing and it was over with so quickly, he was a magician with his hands! It was now time for the final part of the procedure; the nurses began to delicately place my hair follicles in one by one.


With the procedure now finished and my new hairline complete, I was given plenty of time to slowly sit myself up. Dr Rogers then offered me some water and food to help boost my sugar levels. Now that I had my bearings back, Dr Rogers walked me into a quiet room and showed me to a mirror. He then said that he would leave me for a few minutes to look at the hairline. After a few minutes had passed he knocked on the door and asked if I was happy with the outcome, to which I found myself near on speechless! I told him how happy I was with it and continually thanked him for doing such an amazing job. He then asked me to take a seat and began to explain in detail how to care for my new hair each day and gave me a detailed plan on paper. He then gave me a spray that he explained would help to clean any blood away from the surrounding area. After making sure that I was completely happy with the outcome and asking if I had any questions Dr Rogers shook my hand and wished me the best of luck with my new hairline.
