Q) Can lotions be guaranteed to work? A) No, but it is possible to give a good indication of how likely they are to work for a particular individual . In general, lotions work best on thinned areas rather than completely bald areas. The most widely used lotion is Minoxidil - either in its generic form or as Regaine/Rogaine. This substance has proven itself over many years to be an effective aid to both hair growth and in slowing hair loss. It is becoming increasingly well documented that certain additives appear to enhance the effectiveness of minoxidil or have a direct beneficial effect in their own right  

Azelaic Acid Whilst minoxidil promotes hair growth, Azelaic Acid reduces hair loss. A very weak acid, (much weaker than vinegar for example), that is found in some whole grains. Recent studies have shown it to be a very potent inhibitor of the enzyme 5- alpha reductase which is responsible for the formation of DHT - the primary substance responsible for hair loss. Many experts believe that azelaic acid will therefore work synergistically with minoxidil - the azelaic acid reducing hair loss whilst the minoxidil promotes hair growth. Note that exposure to direct sunlight needs to be avoided if using this item as it may cause irritation. Some people therefore apply at night and then apply a minoxidil only item during the day. Progesterone A female hormone added in very small quantities. Its effect is to neutralise the local action of the male hormone derivative DHT which is responsible for hair loss.
