Are madarosis and hypotrichosis the same condition?

Madarosis is the absence of eyelashes and hypotrichosis is abnormal hair patterns. So they are not the same condition.

Madarosis refers to loss of eyebrows or eyelashes. There are dozens and dozens of causes of madarosis, including:autoimmune conditions like alipecia areata or lupus or frontal fibrosing alopeciainfections like bacterial infections, leprosy, syphilis, viruses, fungi, HIVpoor diet, including protein deficiency, zinc, iron and other deficienciesEndocrinological problems, including thyroid problemseye problems, including infections like blepharitisskin problems like psoriasis, eczemas, lichen planusHypotrichosis simply refers to less hair in an area than normally expected. One can have hypotrichoisis of the scalp hair or eyebrow or eyelash or body hair. The term is mostly used to describe refuced density from the time of birth rather than a reduction that develops later in life. Many genetic conditions are associated with hypotrichosis.

Madarosis is the absence or loss of the eyelashes (and sometimes the eyebrows), either as a congenital condition or as a result of an infection.Hypotrichosis (hypo- + tricho- + -osis) is a condition of abnormal hair patterns - predominantly loss or reduction. It occurs, most frequently, by the growth of vellus hair in areas of the body that normally produce terminal hair.The above is taken directly from Widipedia
