In daily practice, hair conditioners can be used in different ways. Instant conditioners are applied immediately after shampooing and rinsed off after a few minutes, while deep conditioners, formulated usually in creams, can remain on hair for 20–30 minutes with an increase in penetration. Blow-drying lotions are another formulation that can be left on the hair because of oil-free. They are very useful for people with fine hair or excessive scalp sebum.
Organo-Modified Siloxane Polymers for Conditioning Skin and Hair
Published in Randy Schueller, Perry Romanowski, Conditioning Agents for Hair and Skin, 2020
Functional siloxanes are used in conditioners, shampoos, mousses, hairsprays, hair colorings, permanent wave applications, and setting lotions. Generally, functional siloxanes help condition the hair to improve wet and dry combing, help retain moisture, heighten luster and sheen, improve manageability, and provide an elegant tactile feel. The term conditioner, in relation to hair grooming preparations, refers to ingredients that aid in enhancing manageability, appearance, and feel of hair. Such ingredients should be capable of acting as a lubricant—reducing combing resistance of wet and dry hair, minimizing tangling, making hair softer and smoother, and improving set retention when styled. These ingredients should also act as antistatic agents to reduce or eliminate flyaway hair (especially from dried-out hair) without producing buildup upon repeated application, as this would cause hair to become lank and dull.
Surfactants in Cosmetic Products

Cationic surfactants or cationics are characterized by having a positively charged hydrophilic group on a nitrogen atom attached to the hydrophobic fatty chain, usually known as the quaternary group (or simply quat) (Surfactant Science Series, 1990). They are often used for their substantivity (adsorption on substrates, for instance, hair and skin). Some important properties of these surfactants make them useful as bactericides in liquid soaps and mouthwashes, and antistatic agents in hair products. Conditioners are products used after hair washing, therefore their formulations do not need to contain anionic surfactants, since most of which are incompatible. This makes it possible to use cationic surfactants as antistatic and conditioning agents for hair fibres in formulations of conditioners, masks and combing creams.

Novel procedures such as LLLT or mesotherapy with PRP are becoming increasingly popular as adjuvant treatments for different types of alopecia (17–24), with some experimental and clinical studies supporting their role in slowing hair loss and promoting hair regrowth. The anti-inflammatory properties of PRP could confer a potential post-operative benefit (25,26); however, further investigation is needed to confirm the benefits of these techniques in the context of hair transplantation., The use of specific products such as shampoos, conditioners, and lotions – preferentially those which have demonstrated safety and efficacy in preclinical and clinical trials - may be considered as adjuvant therapies, especially taking into account their cosmetic effects (27–30). Specific lotions for slowing down hair loss and stimulating hair growth with proven efficacy shown in clinical studies may be considered as an option after hair transplant, especially for non-transplanted areas, while lotions proving efficacy and safety in ex-vivo and clinical studies may be considered in the post-transplantation period to reduce inflammation and aid graft adhesion (28).
Microencapsulated soil conditioner with a water-soluble core: improving soil nutrition of crop root

For acquiring higher yields, most farmers in China have adopted to use more than the standard level of fertilisers, resulting in low utilisation rate of nutrition (Yong et al.2018). It carries the risks about resources wasting, environmental pollution, salt stress and soil structure deterioration (Dawson and Hilton 2011, Zhang et al.2015, He et al.2017, Yang et al.2017). At present, the design of main soil conditioner aims to remedy soil properties, such as using matrices to retain water and nutrient from nature (Saha et al.2017, Wang et al.2018, Saha et al.2019), adopting gypsum for ion exchange (Backes et al.2017, Miranda et al.2018), pseudomonas putida (He et al.2016) and adjusting soil pH value (Jiang et al.2015, Bai et al. 2018). Nevertheless, the challenges about protecting resource and environment cannot be completely solved without evolving the traditional fertilisation pattern. Most fertilisers have lost with water, evaporated by illumination or degraded by microorganism (Xiang et al.2014). In addition, the remainder may play a useless part on cultivated lands or even harmful to them after exhausting the effective constituent of absorbing-type conditioner. Furthermore, the existing conditioner cannot retain nourishment with some amount for a certain time.

Developed in the 1930s, synthetic shampoos contain detergents, which remove sebum/sweat/debris but may cause hair frizz/breakage1. Hair cleansing conditioners (HCCs) (“conditioner washers”/”co-washes”) were designed to address these effects2,3. Recently there have been concerns regarding HCCs produced by WEN by ChazDean (WCD)4–6. Between 2007 and 2014, the U.S Food and Drug Administration (FDA) received a total of 55 complaints regarding WCD HCCs7. Subsequent rates were higher: 2015 (n = 31), 2016 (n = 1,509), 2017 (n = 237), 2018 (n = 132) and 2019 (first quarter, n = 15)4. Over 98% were from female consumers and adverse events (AEs) included: alopecia (88%), pruritus (21%), rash (17%) and hair thinning (10%)4. The majority involved WCD Sweet Almond Mint Cleansing Conditioner (SAMCC)4.
