Journal ArticleDOI
Nanoparticles--an efficient carrier for drug delivery into the hair follicles.
Juergen Lademann,Heike Richter,A. Teichmann,Nina Otberg,Ulrike Blume-Peytavi,Javiana Luengo,Javiana Luengo,Barbara Weiss,Ulrich F. Schaefer,Claus-Michael Lehr,Roger Wepf,Wolfram Sterry +11 more
TL;DR: It was found that the nanoparticles penetrate much deeper into the hair follicles than the dye in the non-particle form, if a massage had been applied and without massage, similar results were obtained for both formulations.
Journal ArticleDOI
Variations of Hair Follicle Size and Distribution in Different Body Sites
TL;DR: The present investigation clearly contradicts former hypothesis that the amount of appendages of the total skin surface represents not more than 0.1% and leads to a differential evaluation of skin penetration processes and a completely different understanding of penetration of topically applied drugs and cosmetics.
Journal ArticleDOI
Penetration Profile of Microspheres in Follicular Targeting of Terminal Hair Follicles
TL;DR: The basis for follicular targeting of essential structures containing stem cells for keratinocytes, melanocytes, and mast cells has been laid and a selective penetration route of the microspheres into the HF is demonstrated.
Journal ArticleDOI
Selective follicular targeting by modification of the particle sizes
Alexa Patzelt,Heike Richter,Fanny Knorr,Ulrich Schäfer,Claus-Michael Lehr,Lars Dähne,Wolfram Sterry,Juergen Lademann +7 more
TL;DR: By varying the particle size, different sites within the porcine hair follicle can be targeted selectively, and the situation can be expected to be similar due to a similar size ratio of the hair follicles.
Journal ArticleDOI
Hair follicles - a long-term reservoir for drug delivery.
Juergen Lademann,Heike Richter,Ulrich F. Schaefer,Ulrike Blume-Peytavi,A. Teichmann,Nina Otberg,Wolfram Sterry +6 more
TL;DR: Interestingly, the storage reservoir capacity of the stratum corneum and the hair follicle infundibulum and canal are compared and it is shown that a 10 times longer storage within thehair follicles is demonstrated.
