Minoxidil is an over-the-counter treatment, often sold under the name Regaine or Rogaine. It comes in the form of a foam or liquid which you massage into the scalp. Most people need to use this medication regularly for around four months to see any benefit.
Finasteride, usually sold under the brand name Propecia, is a prescription tablet taken once day. It works by preventing testosterone in your body from converting into DHT.
Scalp micropigmentation is a non-invasive hair treatment for people who have balding, thinning or receding hair. The doctor essentially gives the patient a medical tattoo that uses little dots to mimic the look of short hair.
But  if you want to slow down hair loss and reduce the likelihood of a hair transplant, it is important to understand the root cause of the problem. For example, if hair loss is the result of work-related stress then a change of job or career could potentially cause your hair to reappear.
The food that you eat and the shampoo you use will also affect the condition of the hair on your head. Hair need sufficient amounts of protein, iron, zinc and B12 to keep it healthy.
Look for shampoos which are engineered to remove any debris such as sebum, fatty acids and environmental residue that might be clogging up your hair follicles and affecting growth. Volumizing shampoos will temporarily give the appearance of a thicker head of hair.
