Why It Happens
Brittle nails in men are often overlooked but can signal underlying health or nutritional imbalances. Unlike women, men may not notice gradual nail changes until breakage or thinning occurs.
Protein Deficiency: Inadequate intake or poor absorption affects keratin synthesis.
Low Zinc or Iron: These minerals are essential for nail strength and cell regeneration.
Frequent Water Exposure: Manual labor or frequent hand washing can dry out the nail matrix.
Undiagnosed Hypothyroidism: Slow metabolism from low thyroid levels can weaken nails.
Age-Related Decline: Circulation and nutrient delivery to extremities may decrease with age.
How to Manage
Boost Protein and Minerals: Prioritize lean meat, legumes, nuts, and iron-rich vegetables.
Protect Hands: Use gloves for chores or frequent water exposure.
Hydrate and Moisturize: Drink plenty of water and apply nail oil to retain flexibility.
Check Thyroid Function: A TSH test may uncover hypothyroidism as a root cause.
Consult a Specialist: A dermatologist or nutritionist can guide treatment if nails remain weak.
With the right nutrients and protection, nail strength can be restored in most men.
