£20.50 / RRP £30.00 / SAVE £9.50
DESCRIPTIONSpectral F7 is the first hair treatment to incorporate astressin-B a peptide that is very long and complex, with a 30+ amino acid sequence, and includes a cyclo-lactam bridge. Astressin-B contains some unusual amino acids, and unlike virtually all peptides in cosmetic use it is particularly difficult to synthesize. This advancement in the art and science of hair solidifies DS Laboratories reputation for developing cutting edge technologies and bringing them to our customers.
