Benefits of Neem Oil
Neem oil is effective for a lot of hair, scalp, and skin related issues. Let us look at some of the major hair health benefits in detail.
Dandruff in hair is a result of dry scalp and sometimes due to naturally occurring fungus, Malassezia globosa. Neem oil due to the presence of azadirachtin has anti-fungal properties and helps to prevent dandruff. The anti-inflammatory properties of this oil also help eliminate many of the conditions that can cause dandruff, including the dry skin on the scalp.  
Not only does this oil help to exfoliate the scalp and eliminate dirt and grime, but it also stimulates the circulation in the scalp, which can improve overall health and oxygenation of those cells. 
Optimal pH levels
Regular use of neem oil not only helps to eliminate dandruff but also helps to maintain optimal pH levels and scalp health. Therefore, it is used in a wide range of shampoos and hair oils.  
When you blend this oil into your shampoo and conditioner, it can help to settle the volume of your hair and eliminate split ends, making your locks easier to manipulate and style. 
It is easier to bid goodbye to frizzy hair with neem oil on your side. Neem is used in various hair conditioners to improve texture and treat damaged hair. Apply neem oil to get improved hair quality and smooth texture. 
The antibacterial, anti-fungal and antiviral properties of this oil make it an excellent and rapid remedy for hair lice that may infect your scalp and hair. Studies have shown the effect of neem oil on the treatment of hair lice. When the neem shampoo was compared to a permethrin-based product to check which treats head lice better, the former won the battle. Various companies use neem as a key ingredient in their shampoos due to this particular property.  
The age-old problem of hair loss can be naturally cured using neem oil. It strengthens the hair follicles and accelerates hair growth. It is also known to fight the problems of hair thinning and hair damage. 
Split ends are one of the important reasons for stunted hair growth. They also spoil hair texture. Applying neem oil to hair will ensure nourishment to hair strands from root to tip and prevent the occurrence of split ends. Regular trimming and applying neem oil is a simple secret to healthy long hair.
