Figure 2: The scalp care active significantly soothes scalp discomfort. After 14 days, all sensory ratings were significantly improved. Parameters of ‘Stinging’, ‘Irritation’, ‘Itchiness’ and ‘Discomfort’ were self-assessed by the subjects, while ‘Redness’ and ‘Visible scalp irritation’ were graded by experts. Within the placebo group the scalp sensory ratings deteriorated compared to baseline and are therefore not represented here. An exception to this is the ‘Itchiness’ rating. Paired Student’s t-test
The scalp care active is exactly targeting the
repairing/improving of scalp sensitivity and the balance of oily scalp. Furthermore, this product is part also of the category of the skinification trend: this substance is already in use in skin care applications. From the in vivo study, in Figure 2, it is
possible to see how consumers feel after the application of a leave-on tonic containing 1% scalp care active for two weeks. All the parameters characteristic of sensitive scalp, such as stinging, irritation, itchiness, discomfort, visible scalp irritation and redness have significantly improved compared to untreated and treated with placebo. This demonstrates how the scalp care active
is able to perfectly answer the requirements of Chinese consumers towards the new need of having products for scalp care, especially related to sensitive scalp.

Thai consumers The demand for hair treatments has surged in Thailand, spurred by the fashion for styles achieved using chemical treatments and heat styling. This is true of both men and women and is due to the impact of South Korean trends and Western vintage hair styles on local tastes. This fashion has led to opportunities for products that address specific scalp issues, such as sensitivity and damage.

Figure 4: Subject assessment (left) confirms the perceptible hair greasiness reduction efficacy of the active. Subjects felt a significant improvement with both 0.5% and 1% of the scalp care active ingredient. On the right side is the expert assessment. Hair greasiness reduction was already decreased after 28 days and the time-dependent efficacy is confirmed by a further reduction after 56 days

Mean + SEM; n= 21/20;
** = p<0.01 In Figure 3, the different hair and scalp issues
among Thai consumers during 2022 are listed. The major concerns among women are hair loss, frizzy hair, lack of volume and dryness. While for men, it is hair loss, grey hair, oily and itchy scalp. In both consumer categories there is some interest for dry, itchy and oily scalp. This trend is particularly evident among millennials, which is illustrated in Table 1. This group of consumers should be
addressed especially with scalp products targeting sensitive scalp. For the scalp care active, the age of the consumer volunteers, who participated in the studies, varied quite widely and also included millennials in the study design. Also from Figure 3 emerges a potential for
products that claim to delay ageing and prevent or minimise hair loss. However, while treatments are in vogue, manufacturers should also
