Some amount of loss of hair is common in males. It's common near temples. It's called Male pattern baldness. You didn't mention the duration of your hair loss. Normally, hair grows after it is lost and it takes upto 3 years to restore your lost hair. Generally hair loss is common after stressful situations or after prolonged fever etc. Taking food rich in proteins like milk, eggs and fresh fruits and leafy vegetables help in growth of hair. Coming to family history of balness, you need not worry much about it. Paternal baldness leads to baldness in sons and grand sons. In your case, it's maternal uncles, so it's not a concern.
Take vitamin D supplements.
And also take sun exposure.
But I don't think taking vitamin D will solve the problems.
You should take treatment to remove the cause of low vitamin D.
You can consult me at lybrate...for homoeopathic treatment..
- The Sun rays has to fall on bare skin for about 15-20 min for the body to make vit d, clothes & sunscreen hinder the effect
- in winter ,upper limbs till elbows & lower limbs till knees can be exposed to sunlight.
Yeah you can take Vit-D3 capsule once a week. For natural methods sunlight is the best source of vitamin-D3. Then milk products can also be preferred. Cheese, egg yolk, salmon fish, tuna, orange juice etc are the dietary sources.
