Vitamin D Deficiency in Winter: Effects on Women’s Hair and Health

Vitamin D deficiency is widespread in the UK during winter due to limited sunlight exposure. For many women, its effects show up quietly through increased hair shedding, reduced hair strength, low energy, and slower recovery rather than immediate illness.

Because hair follicles are highly sensitive to internal changes, vitamin D deficiency often affects hair before other symptoms are noticed.

 

Why Vitamin D Is Important for Hair Growth

Vitamin D plays a role in regulating the hair growth cycle. When levels are sufficient, follicles are more likely to re-enter the active growth phase efficiently.

When vitamin D levels drop:
• hair growth phases shorten
• resting phases extend
• shedding increases
• regrowth becomes slower and finer

This leads to diffuse thinning rather than sudden hair loss.

 

Why Vitamin D Levels Drop in Winter

In winter, vitamin D production decreases because:
• sunlight exposure is limited
• outdoor activity reduces
• dietary intake may not be enough

As a result, deficiency becomes common even in otherwise healthy women.

 

How Vitamin D Deficiency Affects Overall Health

Low vitamin D does not only affect hair. It may also contribute to:
• low energy and fatigue
• weakened immunity
• muscle or joint discomfort
• slower recovery from stress or illness

These internal strains further affect hair growth consistency.

 

Correcting Vitamin D Deficiency to Support Hair

Vitamin Injections

Vitamin injections help restore vitamin levels when oral supplements are insufficient.

They may help by:
• correcting deficiencies more reliably
• supporting hair growth processes
• improving hair strength and texture

 

IV Drip Therapy

IV drip therapy supports a broader nutrient balance during winter.

IV therapy may:
• improve nutrient absorption
• support immune function
• enhance overall follicle resilience

 

When Hair Follicles Need Additional Support

Correcting vitamin deficiency stabilises the internal environment, but follicles that have been under strain for longer may still need regenerative care.

This is when treatments such as:
• PRP hair treatment
• GFC hair therapy
• Exosome hair therapy

are often combined with vitamin support to improve results.

 

Why Early Correction Matters

Prolonged vitamin D deficiency can gradually weaken follicles and slow recovery. Addressing the deficiency early helps prevent seasonal hair loss from becoming long-term thinning.

Conclusion

Vitamin D deficiency in winter affects both hair and overall health in women. When levels drop, hair growth slows and shedding increases, even when scalp care is good.

Correcting deficiencies and supporting follicles together offers the most reliable recovery.
