Vitamin D deficiency as a cause of hair loss? We clarify

Vitamin D is not only important for strong bones and a strong immune system. Studies show that it also plays a decisive role in hair growth. A vitamin D deficiency can therefore not only promote tiredness and susceptibility to infections, but can also trigger or increase hair loss .

But how exactly does vitamin D deficiency affect hair - and what can you do?


The role of vitamin D in the hair cycle

Effect on hair follicles and keratinocytes

Vitamin D directly influences the hair follicles, more specifically the keratinocytes. These cells are crucial for the formation of the hair structure. A sufficient vitamin D level ensures that the hair roots remain active and new hair can be formed in a healthy way.

Influence on the growth process

  • Regulation of the Anagen Phase: Vitamin D supports the active growth phase of hair and helps the hair remain in this phase longer.
  • Regeneration of the hair follicles: It acts as a stimulus for the recovery of weakened or damaged hair roots.
  • Formation of new hair roots: Studies indicate that vitamin D is involved in the activation of stem cells in the hair follicles, which are responsible for the formation of new hair roots.

Conclusion: A lack of vitamin D can disrupt the entire hair cycle - hair falls out more often, while at the same time fewer new hairs are produced.


Causes of vitamin D deficiency

Gradual progression

A vitamin D deficiency often develops slowly and unnoticed. Many of those affected only notice symptoms when the deficiency has been present for some time.

Common reasons for a deficiency

  • Too little sunlight: Particularly in the winter months in Central Europe, there is often not enough sunlight to produce enough vitamin D.
  • Inadequate diet: As only a few foods contain significant amounts of vitamin D, it is often difficult to obtain it from food alone.
  • Intestinal or metabolic diseases: Diseases such as coeliac disease, Crohn's disease or liver and kidney diseases can hinder the absorption or conversion of vitamin D.
  • Age: With increasing age, the skin's ability to produce vitamin D from sunlight decreases.

Symptoms of a vitamin D deficiency

Physical and psychological complaints

A deficiency not only manifests itself in hair loss, but can also cause a range of other symptoms:

  • Tiredness & exhaustion: The body appears generally exhausted and performance decreases.
  • Muscle weakness: Vitamin D is important for the muscles, which is why a deficiency is often associated with loss of strength.
  • Mood swings: As vitamin D also affects serotonin levels, a deficiency can promote depressive moods.
  • Increased susceptibility to infections: Vitamin D plays a central role in the immune system - a deficiency weakens the body's own defenses.
  • Brittle nails & dry skin: Skin and nails also show clear signs when the supply is inadequate.

Vitamin D deficiency hair loss: diagnosis and treatment

How is the defect determined?

The diagnosis is made via a blood test at the doctor's, in which the 25(OH)-vitamin D value is measured.

Optimal reference range

  • 40-60 ng/ml is considered a healthy target value
  • Below 30 ng/ml one speaks of a deficiency

Treatment options

  • Vitamin D supplements in drop or capsule form
  • Regular sun exposure (10-20 minutes a day in summer)
  • Diet with vitamin-rich foods such as salmon, egg yolk or mushrooms

Note: Supplementation should be supervised by a doctor, as an overdose can be harmful.

Vitamin D and holistic hair care

Why vitamin D alone is often not enough

A vitamin D deficiency can increase hair loss - but it is rarely the only cause. There are often several factors at play: Hormones, stress, diet, genetics and scalp health.

It therefore makes sense:

  • Medical clarification of deficiencies
  • Holistic measures for hair roots and scalp
  • Combination of internal care (vitamins) and external care (serums, massages, gentle care products)

Tip for sustainable results

A high-quality hair serum can optimally complement the effect of vitamin D therapy by strengthening the scalp and providing additional external support for hair growth.


Conclusion: Hair loss due to vitamin D deficiency should be viewed holistically

Vitamin D deficiency can be a decisive factor in hair loss. For this reason, vitamin D levels should also be checked by a doctor if hair loss persists.

At the same time, a holistic approach is worthwhile: In addition to internal supplementation with vitamin D, high-quality hair serums can also play an important role. The Laduti Hair Growth Serum combines biotin, caffeine, plant extracts, vitamins and modern active ingredients such as Procapil™ and AnaGain™. These ingredients can additionally strengthen your hair roots, soothe your scalp and support the natural hair structure – all without hormones or harsh chemicals.

This provides a clever combination: Internal nourishment plus external revitalization to keep hair healthy and strong in the long term.

FAQ

Can vitamin D deficiency alone cause hair loss?
Yes, diffuse hair loss in particular can be promoted by a deficiency. However, several factors usually work together.

How quickly does hair grow back after vitamin D supplementation?
It usually takes several months for the hair cycle to stabilize. Patience is crucial.

Should you have your vitamin D levels tested regularly?
Yes, a blood test by a doctor provides information about the actual vitamin D level and helps to find a targeted and safe dosage of supplements.

Is sunlight sufficient to cover the vitamin D requirement?
Often yes in summer - but not in winter in Central Europe. Supplementation is therefore advisable here.

What role do hair serums play despite vitamin D deficiency?
Serums can nourish the scalp and strengthen the follicles, which can be particularly useful during periods of deficiency. However, they are no substitute for medical care.
