What Is Christmas Tree Pattern Hair Loss

Written by Rali Bozhinova, Superintendent Trichologist, The Belgravia Centre

You might have heard of patterned hair loss, but have you heard of hair loss in a Christmas tree pattern? Unlike your Christmas tree, this type of hair loss can remain visible for much longer than just the Christmas period, but we are here to help.

What Is A Christmas Tree Pattern Hair Loss?

If you have Christmas tree pattern hair loss (also known as Olsen pattern), you will notice gradual thinning of your hair across the top of your scalp. When you part your hair in the middle, you may see your scalp more easily through the hair. Your parting will be wider at the front part of the scalp, giving the hair thinning a triangular shape resembling a Christmas tree with the stem of the tree at the very front of your scalp, and the top of the tree around your crown.  However, your hair will be thicker at the lower sides and back of your head.

This pattern of hair loss is more common in women and is also called female pattern hair loss, or androgenic alopecia. Each woman is different and not everyone’s hair loss will resemble a Christmas tree. Some women may lose hair mainly on their temples and crown; others may only experience hair loss on their crown and preserve the front hairline. The Christmas tree pattern is just one possible presentation of female pattern hair loss.

Why Does It Happen?

Female pattern hair loss (FPHL) is very common. It is a genetic type of hair loss that can start at any age after puberty. For some women, it starts in their late teenage years, whilst for others, it may not start until after menopause.

Your genes will make you more susceptible to this type of hair loss however, there is a lot more to it. The hormone responsible for FPHL is dihydrotestosterone (DHT). Your male sex hormone testosterone converts into DHT in the presence of 5-alpha-reductase enzyme that is found in the scalp. DHT is the most potent type of androgen, or male sex hormone. When DHT is produced in the scalp, it starts attaching to androgen receptors found in specific follicles that are distributed across the top of your scalp.

This process causes many changes in the affected follicles and they start miniaturising. This means that these follicles become smaller over time. If they used to produce 4 hair strands before, they may only make a single hair strand now that is also thinner in diameter. The affected hair will grow slower and may fall more easily before it reaches its usual length. Then the follicles may remain empty for longer before they produce new hair.

All of this can worsen over time and often some follicles can be permanently lost. The more the miniaturisation process progresses, the thinner the hair looks on top of the scalp, resembling a Christmas tree pattern.

 

What Other Conditions Can Make This Worse?

For many women FPHL does not have any obvious medical trigger apart from a family history of hair loss. However, for others, certain medical conditions and hormonal changes may aggravate the FPHL further.

Dietary Deficiencies

The cells in your hair follicles require energy to divide and make hair fibre. This energy is coming from the nutrients you absorb from your diet. Any deficiency, especially iron and vitamin D deficiencies, can have a negative impact on the hair growth cycle, slow down hair growth, or cause telogen effluvium. FPHL is often aggravated in the presence of telogen effluvium, a condition that causes excessive hair shedding.  

Some Medications

Some medications can cause hair loss as a side effect. Common examples include retinoids, immunosuppressants, and some hormonal treatments. In most cases, this is only temporary but sometimes, this can aggravate underlying conditions such as FPHL

Sudden Weight Loss

Calorie deficit diets or unexplained weight loss can result in poor nutrient intake and multiple vitamin and mineral deficiencies such as low ferritin, iron, vitamin D, B12, and folate. All of these are important for a healthy hair growth cycle, healthy skin, and healthy hair.

Various Stressors

Emotional stress can affect you in many ways and can cause a change in your hair growth cycle. If you have an extremely traumatic experience, you may notice increased hair shedding two to three months later because many follicles may prematurely shift to their end stage of the hair cycle, causing excessive hair shedding. This is often temporary, however, multiple stressors can prolong the shedding period.

Androgen Excess

High levels of androgens, or male sex hormones, may result in more testosterone and therefore, more DHT being converted in the skin. This can cause symptoms such as acne, increased facial or bodily hair, as well as hair loss. When androgen excess is left unmanageable, it is likely to speed up the FPHL progression.

Polycystic Ovarian Syndrome (PCOS)

PCOS is common and can cause irregular menstrual cycles, high levels of androgens, oily skin, acne, weight gain, facial hair, polycystic ovaries, and hair loss. The type of hair loss most commonly seen in women with PCOS is female pattern hair loss because both conditions are associated with the same hormones. There are genetic factors that can make you more likely to develop PCOS and FPHL, and often changes in lifestyle can be helpful to manage the symptoms.

Abnormal Thyroid Function

The function of your thyroid gland is vital for your energy, metabolism, and overall functions of your body. When your thyroid gland is overactive, you may experience excessive hair shedding; and when it is underactive, your hair wouldn’t have enough energy to grow. Either way, this can result in hair loss and a number of other unpleasant symptoms such as changes in your weight, energy, mood, and appetite.

Menopause

This is a time when your body goes through significant hormonal changes. Your oestrogen reduces and the balance between the male and female sex hormones changes. This comes with an array of symptoms such as dry skin, difficulty sleeping, anxiety, weight gain, hot flushes, and often – hair loss. FPHL is commonly seen after menopause and if you already had mild signs of FPHL, the hormonal changes associated with menopause may aggravate this further.

 

How To Get Rid Of The Christmas Tree In Your Hair?

If you notice any signs of hair loss, always consult with a specialist before you start any medication. They will help you diagnose your hair condition, and discuss suitable treatment plan for your specific case.

Minoxidil

Topical minoxidil is the only MHRA-licensed and FDA-approved medication for female pattern hair loss.

When applied to the scalp, it increases blood circulation, bringing more nutrients and oxygenated blood to the hair follicles. Minoxidil helps the follicles to remain in their actively growing phase of the hair cycle, encouraging stronger and longer hair growth. It helps the follicle grow bigger and therefore produce multiple hair strands, increasing the hair count across the scalp. The Belgravia Centre’s pharmacy offers various minoxidil preparations in liquid or cream forms, with different formulations, minoxidil strengths, and added hair growth supporting ingredients. This helps us tailor the treatment to each individual case, depending on medical history, lifestyle, and severity of hair loss.

Low Level Laser Light Therapy

The HairMax Laser products are FDA-cleared devices that use photobiostimulation technology. The laser light penetrates the scalp and reaches the bottom of the hair follicles, called derma papillae. The laser light helps to grow fuller and thicker hair, and reduce the hair thinning process in cases of androgenic alopecia.
