Cleansing of Hair
Published in Dale H. Johnson, Hair and Hair Care, 2018
Excessive build-up of sebum on the hair manifests itself in ways that make the hair unappealing to the eye and unpleasant to the touch. The “rats-tails” effect, which is commonly associated with greasy hair, is a result of hair fibers clumping together, and is perhaps the easiest to recognize. Interfiber adhesion is a major contributor to the loss of hair body (36) resulting in the compression of the volume of the hair mass and retarding the ability of the hair to bounce. It also helps to amplify the actions of diffused light scattering and reduces the sheen and luster of the hair (37,38). Precisely how the sebum acts on hair aesthetics, however, is a complex phenomenon dependent on a number of factors. One of these factors is believed to be related to the viscoelastic properties of the sebum (39,40). Using oil as hair soil, Dobinson and Peter (39) were able to show that both the tactile and visual perception of hair greasiness increase with the viscosity of the oil. Another factor is the specific composition of the sebum. In one study, Bore et al. (41) found that oily hair and dry hair differ in the contents of unsaturated fatty acids. In another study, Koch et al. (42,43), based on analysis of hair clippings collected on human heads, were able to show that the perception of hair oiliness tends to increase with the amount of wax esters and monoglycerides, but decrease with the ratio of saturated to unsaturated fatty acid, and with the amount of cholesterol esters.
Thalassotherapy and Marine Cosmeceuticals
Published in Leonel Pereira, Therapeutic and Nutritional Uses of Algae, 2018
Phymatolithon calcareum (as Lithothamnium calcareum) is a calcareous marine alga whose thallus is used in the treatment of decalcification, osteoporosis, painful joints, chronic tiredness, painful stages of rheumatism, gingivitis, stomach pains, and in anti-acid cures. Lithothamnium and Fucus enter frequently in the composition of sacks used in thalassotherapy. Among other marine macroalgae, rockweed (Fucus vesiculosus) has also proved effective against excess weight for individuals with a normal appetite. Rockweeds have furthermore an anti-seborrheic effect on greasy hair (Charlier 1975, 2002).
Hair cosmetology

The development of personal hygiene, practicing sport or exercise, living in a highly polluted city, or humid ambient air result in increasingly frequent shampooing. Regardless of the issue, be it excessive sweating, greasy hair, density of airborne pollutant particles, or coating related to leave-on hair care or dressing products, the need for detergency is not as high when shampooing every second day or less, but high enough for cleansing hair likely more exposed or prone to collect more soil. This type of shampoo is based upon the combination of anionic and amphoteric surfactants selected for suitable mildness and tolerance. Another requirement is fine tuning its conditioning potency (i.e., favoring ease of combing and yielding a beautiful head of hair but without causing any buildup of polymer film deposit and its resulting effect of weighing hair down).

After 5 more days without washing their hair (T17) (Figures 4 and 5), the patients returned to be reevaluated and at trichoscopy, the excellent therapeutic results obtained with the use of the tested shampoo were totally maintained over time in 60% of the patients and partially maintained in 40% of them, with one patients (10%) presenting yellow scales on the scalp and three patients (30%) having an excess amount of sebum on hair/scalp. Trichoscopy at 70× magnification showed no changes compared to T12 in nine subjects (90%) and a moderate increased number of dilated capillaries only in one subject. Clinical improvement after the use of the tested shampoo was also sustained over time, with no patient with flakes or scales on hair and scalp (Figure 6) and only two subjects complaining of greasy hair. Reduction of symptoms continued to be documented in all the patients, with irritation/itching remaining absent in nine patients and reduced in one.

Emma: I don’t know maybe I think they think I am unhygienic and not looking after myself. You know, how boys or girls might be like, “Oh, she’s got dead greasy hair like she doesn’t shower.” They might think the same like, “Oh, she’s not taking care of herself, like going to the toilet when she needs to go.” So maybe that’s why.

AEs related to topical KTZ occurred in 5–32% of the treated population. All AEs were mild to moderate; there were no serious AEs reported. The most common AEs for topical KTZ are pruritus, dry skin, and burning sensation. Dry hair and greasy hair are also reported with KTZ shampoo use.
