SEBACEOUS SCALP - Oily Scalp
Sebaceous hyper-secretion is a pathology of the scalp due to an excessive production of sebum caused by the hyperactivity of the sebaceous glands. Some of the most frequent symptoms include: head itch, acrid odor and yellowish color. Seborrhea sometimes evolves into seborrheic dermatitis a condition in which excess sebum is accompanied by an inflammation of the scalp which reacts producing oily flakes in the hair and can be easily misunderstood as being dandruff but differs in some aspects: the flakes are usually larger, conglobate, generally oily and yellowish in appearance and the scalp skin appears light red. Usually not only the hair and scalp are affected but also eyebrows and face are. Another scalp anomaly related to seborrhea and Hyperhidrosis can be determined by excessive sweating of the sweat glands. Hyperhidrosis is due to physical genetic causes and above all to the emotional attitude we generate during our life processes. The skin is very delicate, easily irritable and almost always congested by blood vessel stasis. The indiscriminate use of shampoo with too much detergent, harsh and toxic ingredients over activates the sweat glands which can cause excess sweating. The more the hair is washed and the more it’ll become greasy.
This can commonly occur with long hair when your scalp is oily and gets flaky but your ends are dry. Your roots get greasy and limp easily, while the ends of your hair remain dry and rough.
Dry scalp is a problem often associated with a sensation of itching, discomfort or a burning sensation. In most cases this symptom is due to the lack of skin lipids and / or dehydration. The alteration of the hydro-lipid’s correct balancing may be caused by a dysfunction of the sweat and / or sebaceous glands which do not produce sufficient water and sebum. A dry scalp can also depend on external factors such as and due to the use of treatments that force the disintegration of the keratin or due to the use of extremely aggressive detergents. The dry skin will look like a dry flake (dandruff) which will create an intense flaking from the scalp. It often appears with thru the detachment of whitish flakes of dry and dead skin at the base of the hair due to an excessive epithelial cell turnover (keratinocytes). A symptom that usually accompanies the dandruff is itching. The causes can beseveral such as; a genetic predisposition, a physical and/or emotional stress, hormonal changes, dry or greasy skin, increased sebum secretion or wrong eating habits (ex.excessive consumption of fats, abuse of alcohol, a poor diet of foods rich in zinc, lack of vitamin B etc. Dandruff can be related also to the irritation caused by some hair care products and a more severe form of dry flakes such as psoriasis can often be confused with dandruff or with seborrheic dermatitis and is characterized by the presence of patches that remain localized on the scalp without extending to other parts of the body. These patches thicken and create a crust as time goes by and can sometimes also affect the temples, the back of the neck and the ears. The psoriasis of the scalp is in no way related to hair loss but often present in very nervous people and can cause an intense and annoying itching.
There are many forms of alopecia. The most known is the androgenetic alopecia which due to an excess of DHT (dihydrotestosterone a hormone harmful to the hair follicle) and is characterized by the loss of hair on the front and upper areas of the head. This disorder mainly affects men and can also develop in very early during sexual maturation. Women can be affected by alopecia especially when going thru the menopause. The stem gets thinner, the hair is becomes less bright and then the stems begin to break and the hair falls off.
