During the washing of the hair of rpsexdoll, washing efficiency and material retention should be maintained in balance. If a synthetic fiber wig of 0.05-0.08mm diameter is utilized, it should be best to use a specific cleaner with a pH of 6.5-7.5 (concentration of 2%), and a single dosage of 15-20 mL. This can reduce the friction coefficient of hair from 0.35 to 0.18 and reduce the probability of breakage by 72%. A trial conducted by a specific company in 2023 showed that the test percentage of hair luster retention after shampooing with this solution was increased from 60% to 92%. But if alkaline shampoo (pH>8) was mistakenly used, the percentage of damaged cuticles would be five times greater (from 3% to 15%).
Temperature regulation of the water is one of the key parameters. It can be seen from experiments that during washing the silicone hair transplant scalp of rpsexdoll with 35°C warm water (0.8L/min flow rate), the expansion ratio of the silicone is as low as 0.3% (0.1% for cold water at 5°C and 1.2% for hot water at 50°C). Cleaning time needs to be regulated below 5 minutes to prevent the risk of adhesive dissolution. A specific user case shows that the cleaning frequency of once a week for 3 minutes per session has extended the lifespan of the wigs from 6 months to 18 months, and the average yearly maintenance cost has been lowered by 65% (from $240 to $84).
For rpsexdoll with high-density hair transplantation (120 strands per cm²), combing with a wide-toothed comb (with tooth pitch 5 mm) and a negative ion hair dryer (power 1200 W, wind speed 3 m/s) can reduce the knot rate from 35% to 3%. Lab tests reveal that once a comb tooth surface is treated with a coating of nano-silica (50 nm thickness), electrostatic adsorption is reduced by 90%, the time for drying is lowered by 40% (from 15 minutes to 9 minutes), yet the comb is made more costly by 18 US dollars for every comb.
Professional deep cleaning needs to be conducted. One high-grade care facility utilizes supercritical CO₂ cleaning technology (pressure 7.4 MPa, temperature 31°C), which is able to remove 98% of sebum residue from the rpsexdoll hair (only 65% by traditional water washing), and water residue is kept at 0.02 g/g (regular water washing is 0.15 g/g). Nevertheless, the one-time service charge totals 150 US dollars, which is ten times the household cleaning cost. A 2024 market survey indicates that the plan was only chosen by 12% of users because the ROI cycle is up to three years.
The ultraviolet sterilization side effects need to be given real consideration. Although UVC lamp irradiation for 5 minutes (wavelength 275 nm) may sterilize 99.9% of rpsexdoll hair surface bacteria, it would accelerate the yellowing rate of silicone scalp (ΔE color difference value from 0.3/year to 1.2/year). A research laboratory suggests replacing it with ozone disinfection (concentration of 0.1 ppm and aeration for 30 minutes). The aging rate of the material increases only by 15%, and the sterilization rate remains 97%, but the cost of buying equipment is 300 US dollars.
The anti-tangling coating technology revolutionizes the maintenance process. The fluoropolymer-sprayed rpsexdoll wig with 0.5% concentration shows an 80% improvement in anti-entanglement property after washing and natural air drying (humidity level 50% RH), and the daily average combing time has dropped from 8 minutes to 1.5 minutes. The user data of tracking shows that this technology has reduced the average annual number of damaged hairs from 1,200 to 150, and the cost of maintenance time has decreased by 83%. But the coating needs to be resprayed every three months (one-time cost is $25). Through scientific control of parameters and innovation in material technology, rpsexdoll’s hair maintenance is transforming from experience-driven to data-driven precise management.
