research Boron deficiency responses in maize (Zea mays L.) roots

November 2023 in “Journal of plant nutrition and soil science”

This study observed that maize plants, including a root hairless mutant variety, did not exhibit typical root growth or compensatory foraging behavior under severe boron deficiency in soil, indicating atypical responses compared to other plants.

research A study of the role of root morphological traits in growth of barley in zinc-deficient soil

95 citations , July 2007 in “Journal of Experimental Botany”

This study found that the superior growth and higher zinc uptake of wild-type barley compared to its root-hairless mutant in zinc-deficient soil is mainly due to greater root surface area from root hairs.

research Effects on swine of unilateral neutron irradiation, calcium, and zinc.

3 citations , July 1969 in “PubMed”

This study found that unilateral neutron irradiation in pigs significantly decreased the uptake of radioactive zinc in blood, impaired growth, and led to decreased organ weights and hair pigmentation changes on the irradiated side.

research Single hair analysis by X-ray fluorescence spectrometry detects small changes in dietary zinc intake: A nested randomized controlled trial

11 citations , March 2023 in “Frontiers in Nutrition”

This study found that a modest increase in dietary zinc over six months resulted in a detectable increase in sulfur and zinc counts in individual hairs, suggesting a non-invasive method to monitor zinc intake effects.

research Zinc responsive dermatopathy in goats: two field cases.

10 citations , July 2000 in “PubMed”

This case report suggests that increased dietary calcium from alfalfa may have contributed to zinc deficiency in two adult female goats by blocking zinc absorption.

community Has anyone used zinc as a treatment?

24 upvotes 1 year ago

Zinc is not effective for hair loss unless there's a deficiency. Finasteride and minoxidil are recommended treatments.

community PSA: Check your vitamin D levels!

319 upvotes 1 year ago

Low vitamin D levels can negatively impact hair growth, and supplementing with vitamin D, along with treatments like finasteride and minoxidil, may help improve hair health. Quitting smoking and ensuring adequate vitamin B12 and K2 intake are also suggested to support hair regrowth.

Why is zinc important for preventing hair loss and supporting hair follicle function? Zinc is crucial for hair follicle health, supporting growth and repair processes.
Should zinc be taken orally or applied topically for better results in hair growth? Oral zinc supplementation is generally more effective for promoting hair growth than topical application.
Can a zinc deficiency directly cause hair thinning or increased shedding? Studies link low serum zinc to diffuse shedding and alopecia areata, and severe deficiency states cause hair loss that reverses when zinc is replaced. The evidence is mostly observational, the one supplementation study was small and uncontrolled, and zinc is not a treatment for pattern hair loss.
