As the name suggests, fish oil is a dietary supplement derived from fish. It is extracted from fish tissue and sometimes even the liver. Omega 3s is the crucial element of fish oil that can do miracles. Omega-3s is a polyunsaturated fatty acid that contains different DHA portions ( docosahexaenoic acid) and EPA( eicosapentaenoic acid).

Our body does not produce Omega 3s fatty acids, so we need to supply them from outside, mainly as a dietary supplement.

Fish oil comes from oily fishes like tuna, salmon, mackerel, and herring. You don’t need to worry as fish oil is also available in capsules.

1. Hair growth

Your hairs grow in four phases: anagen, catagen, telogen and exogen. Anagen is the phase where the hair grows. Fish oil essentially causes the hair to enter its growth phase and stay there for a more extended period. It thereby promotes hair shaft growth.


2. Reduction in hair loss

The telogen phase is the one where your hair falls. Fish oil is assumed to reduce this phase to prevent hair loss and increase the hair density.

The DHA present in omega-3s reduces atopic dermatitis and oxidative stress. So fish oil is also theorized to prevent hair loss by oxidative stress.


3. Improvement of scalp health

The antibacterial property of fish oil prevents bacterial invasion in your scalp. It blesses you with a dandruff-free scalp. It prevents your sculpt from being dry and flaky by maintaining the oil balance. It improves hair by keeping your scalp clean. Conditions like dermatitis and skin ageing are also staved off.
