Welcome to the Hair Hub

Hair health often reflects what is happening inside the body. Here we look at the hair growth cycle, how hair is structured, and the most common factors behind thinning and hair loss.

Quick read

Causes of hair loss

At DRV+ we are committed to supporting your health, including your hair and scalp health, no matter the cause. To fully recover from hair loss, thinning and scalp issues, you need to understand the root cause and tackle the problem head-on. There are many reasons for hair loss and poor hair and scalp health, which may include:

Stress

Stress

Stress plays a big role in hair loss. The stress hormone cortisol disrupts the hair growth cycle and reduces the blood nutrient supply to the hair follicles, causing hair thinning.

Medicine

Medicine

Medications including blood thinners, beta-blockers, antidepressants, some anti-seizure medicines, retinoids (high-dose vitamin A) and certain hormonal contraceptives, can all contribute to reduced hair growth, hair loss or thinning.

UV damage

UV damage

Excessive sunlight exposure to the scalp can weaken the hair shaft. Ensure you wear a sun hat to cover the scalp in times of excessive sun exposure.

Hormone imbalance

Hormone imbalance

Hormonal imbalances, especially an increase in the toxic form of testosterone (dehydrotestosterone) and a decrease in oestrogen and progesterone. Menopause is a time when women notice some hair thinning and loss. Menopause support supplements and an inclusion of phytoestrogenic foods may be helpful.

Autoimmune alopecia

Autoimmune alopecia

When autoimmune antibodies attack the hair follicles and cause hair to fall out. To really improve this condition, the immune system needs to be calmed down and the hair follicles need additional support. If you have autoimmune alopecia, we recommend you seek professional help.

Nutrient deficiencies

Nutrient deficiencies

Nutrient deficiencies especially in iron, iodine, zinc and biotin, can slow down hair growth and can cause hair thinning. Iron is needed for normal blood flow to the scalp.

Harsh hair treatments

Harsh hair treatments

Harsh hair treatments such as bleaching, perms and overuse of heat styling damage the hair shaft or the hair root. Ask your stylist if there are gentler ways to get the look that you desire.

Thyroid disorders

Thyroid disorders

The thyroid is responsible for regulating the metabolism. If the thyroid is not working to its full potential, hair growth won’t be at its full potential.

Fungal and bacterial infections

Fungal and bacterial infections

Infections can affect the scalp and damage the hair follicles, leading to bald patches or thinning. Some topical solutions may help in killing the infectious pathogens; however, you will need to support your immune system and the hair follicles themselves.

Inflammatory skin conditions

Inflammatory skin conditions

Conditions such as psoriasis, eczema, and seborrhoeic dermatitis are induced inflammations, either due to autoimmune antibodies or elevated histamine levels which can affect hair.

Chemotherapy and radiotherapy

Chemotherapy and radiotherapy

Chemotherapy and radiotherapy destroy quickly dividing cells in an attempt to destroy cancer cells. Hair is also a quickly dividing cell, and such therapies can cause hair loss.

Crash diets and rapid weight loss

Crash diets and rapid weight loss

When crash diets are undertaken, or rapid weight loss occurs, it creates an environment of stress in the body. Since hair growth isn’t necessary for survival, it won’t be a priority for the body.

Compulsive hair-pulling disorder

Compulsive hair-pulling disorder

Compulsive hair-pulling can affect both adults and children. Adults may need professional therapist support to get to the root cause of the problem. Children may need to be given another way to comfort themselves or take out their frustration.

Diabetes and polycystic ovary syndrome (PCOS)

Diabetes and polycystic ovary syndrome (PCOS)

PCOS, insulin resistance, and diabetes can increase the level of testosterone, which can lead to male pattern baldness in men and women.

Traction alopecia from hair loss from tight hairstyles

Traction alopecia from hair loss from tight hairstyles

When hair is constantly pulled out from hairstyles (braids, ponytails, extensions), the eventual result may be bald patches. Experiment with different hairstyles that don’t pull on the scalp. Some topical and supplemental therapy may be needed to encourage hair regrowth.

Eating disorders including anorexia or bulimia

Eating disorders including anorexia or bulimia

Nutrient deficiencies often result in cases of eating disorders and may cause hair growth to slow down.

Burns, surgery or severe trauma can induce localised hair loss

Burns, surgery or severe trauma can induce localised hair loss

Unfortunately, hair loss due to tissue damage and scarring tends to be more permanent.

Exposure to toxins such as heavy metals or industrial chemicals

Exposure to toxins such as heavy metals or industrial chemicals

Environmental toxins (lead, arsenic) may cause direct damage to the hair follicles as well as indirectly by causing oxidative damage.

Hair growth phases

Anagen (growth phase)

This is the active phase of hair growth, which lasts 2-7 years. About 85-90% of hair follicles are in this phase at any given time.

Catagen (transitional phase)

This short phase lasts 2-3 weeks, during which hair growth stops, and the hair follicle shrinks.

Telogen (resting phase)

Lasting around 3 months, this phase results in the shedding of hair. About 10-15% of hair follicles are in the telogen phase at any time.

Androgenetic Alopecia (AGA)

The most common cause of hair loss, also known as male-pattern baldness in men and female-pattern hair loss in women. It’s typically caused by genetic sensitivity to androgens (male hormones), particularly dihydrotestosterone (DHT), which shortens the anagen phase and causes hair follicles to shrink. A history of hair loss in the family increases the likelihood of developing androgenetic alopecia.

Hair anatomy

The physiology of hair growth and loss

Telogen effluvium: Often triggered by significant hormonal changes, including pregnancy, childbirth, menopause, or the use of birth control. It leads to diffuse shedding of hair, typically 2-3 months after the triggering event.

Polycystic ovary syndrome (PCOS): Hormonal imbalances in PCOS can lead to an increase in androgens, resulting in thinning or loss of hair, especially along the temples and crown.

Thyroid disorders: Both hypo and hyperthyroidism can result in hair thinning or hair loss due to the disruption of metabolic and hormonal regulation.

Alopecia areata: An autoimmune condition where the body attacks hair follicles, leading to round patches of hair loss.

Scalp infections: Fungal infections, such as tinea capitis, can cause hair loss, often with scaling or inflammation of the scalp.

Anemia: Iron deficiency anaemia and other types of anaemia (e.g. Vitamin B12 or folate deficiencies) can contribute to hair loss because of insufficient nutrients required for hair follicle function.

Chronic illnesses: Conditions like lupus, diabetes, and certain types of cancer can cause hair thinning due to inflammation or the use of medications like chemotherapy.

The evidence behind DRV+

Hair Health

Stronger, healthier hair with consistent use

Hair Saviour® is a comprehensive blend of clinically studied vitamins, minerals and botanicals, formulated to support hair strength, growth, condition and thickness - for those who commit to consistent daily use.

76 respondents (from 194 surveyed) 2024-2025 Cross-sectional customer survey
79% found it effective
87% saw improvement in 1+ area
55% would recommend it
Study Findings

We surveyed 76 customers who had taken Hair Saviour® daily for two months or more - long enough to reflect the hair-growth cycle - tracking strength, growth, condition and thickness.

The results?

78.9% rated Hair Saviour® effective. 86.8% noticed improvement in at least one area - most often hair strength (68.4%) and condition (60.5%) - and 54.7% reported new hair growth. Notably, not one person who saw a physical hair improvement rated the product 'not at all effective'.

What This Means

Strength and condition first

68.4% saw stronger hair and 60.5% better condition.

The two most consistently reported improvements across users.

New growth is achievable

54.7% reported new hair growth.

A meaningful result, since new growth is the slowest hair benefit to appear.

Consistency is everything

Most users saw results between 4 and 8 weeks - some longer.

Hair works to its own cycle, so daily use for at least 2-3 months gives it the best chance.
