As is the case with almost any ingestible, even keratin hair supplements need to be used moderately and only as instructed on the label. It is necessary for you to take the advice of a doctor if you have any doubts regarding the use of keratin supplements and whether they would suit your hair or not. The risk factors of using keratin supplements in excess are as follows:


Since keratin is a protein, taking it in excess can result in excessive protein within the body resulting in a condition known as Proteinuria. It is a condition that is characterized by excessive amounts of protein in human urine. Excessive protein within the body might take a toll on the kidneys because of the pressure of extra work exerted on the kidneys. This might also result in renal insufficiency. If renal insufficiency is left untreated, it might result in complete failure of the kidney.


This is a condition caused due to the body making excessive keratin or ingesting excessive keratin. This condition might manifest as thick, rough dry skin and coarse hair texture. Therefore, the use of keratin hair supplements must be stopped if individuals identify the symptoms of hyperkeratosis.


From the above illustration, it can rightly be said that keratin supplements are definitely effective for hair growth but at the same time they must be taken moderately in order to avoid unwanted problems.
