1. A dual dispenser comprising a first pump in liquid communication with a first receptacle, a second pump in liquid communication with a second receptacle, and a common dispenser head, said common dispenser head comprising an output channel forming a dispensing orifice, said output channel being fed with a first and second composition coming out of the first and second pumps; wherein the first pump is operatively associated with a first actuating rod and the second pump is operatively associated with a second actuating rod;wherein the first actuating rod has a longer travel path than the second actuating rod;wherein the common dispenser head comprises a pivoting member which forms two support elements for simultaneously moving the two actuating rods over an axial height corresponding to the shorter travel path, the support elements then continuing their movements by pivoting/rotation of the pivoting member to finish the longer travel path;wherein the first receptacle comprises the first composition, the first composition comprising a volatile solvent and a first fragrance;wherein the second receptacle comprises the second composition, the second composition comprising a carrier and a plurality of microcapsules. 2. The dual dispenser of claim 1, wherein the two support elements are integral with each other in movement. 3. The dual dispenser of claim 1, wherein the two support elements are integral with the output channel. 4. The dual dispenser of claim 1, wherein the two support elements extend on either side of the output channel, advantageously symmetrically. 5. The dual dispenser of claim 1, wherein the two support elements pivot around the output channel. 6. The dual dispenser of claim 1, wherein the pivoting member comprises at least one thrust transmission zone, so that an axial thrust exerted on said thrust transmission zone first causes the translatory movement of the two support elements and of the output channel over the shorter travel path, then a slight rotation of the output channel around its own axis and the pivoting of the support elements to finish the longer travel path. 7. The dual dispenser of claim 6, wherein the common dispenser head comprises a cover which comes in supporting contact on the thrust transmission zones. 8. The dual dispenser of claim 7, wherein the output channel comprises a thrust transmission zone near each of the ends thereof. 9. The dual dispenser of claim 8, wherein the support elements extend substantially perpendicular to the output channel between the two thrust transmission zones. 10. The dual dispenser of claim 1, wherein the first actuating rod having the longer travel path is connected to the output channel closer to the dispensing orifice than the second actuating rod having the shorter travel path. 11. The dual dispenser of claim 1, wherein each actuating rod is topped by a cap defining a support plate for the respective support element thereof, and a connector fitting receiving a flexible conduit which connects the output channel. 12. The dual dispenser of claim 1, wherein the plurality of microcapsules encapsulate a second fragrance. 13. The dual dispenser of claim 1, wherein the microcapsules comprise a shell comprising a material selected from the group consisting of polyacrylates; polyethylenes; polyamides; polystyrenes; polyisoprenes; polycarbonates; polyesters; polyureas; polyurethanes; polyolefins; polysaccharides; epoxy resins; vinyl polymers; urea cross-linked with formaldehyde or gluteraldehyde; melamine cross-linked with formaldehyde; gelatin-polyphosphate coacervates optionally cross-linked with gluteraldehyde; gelatin-gum Arabic coacervates; cross-linked silicone fluids; polyamine reacted with polyisocyanates; acrylate monomers polymerized via free radical polymerization; silk; wool; gelatine; cellulose; proteins; and combinations thereof. 14. The dual dispenser of claim 13, wherein the microcapsules comprise a polyacrylate shell. 15. The dual dispenser of claim 1, wherein the microcapsules have a median volume-weighted particle size of from 2 microns to 80 microns, preferably from 10 microns to 30 microns, more preferably from 10 microns to 20 microns. 16. The dual dispenser of claim 1, wherein the volatile solvent comprises ethanol. 17. The dual dispenser of claim 16, wherein the first composition comprises 0.01% to 98%, by weight, of ethanol. 18. The dual dispenser of claim 1, wherein the carrier comprises water. 19. The dual dispenser of claim 18, wherein the second composition comprises from 5% to 95%, by weight, of water. 20. The dual dispenser of claim 1, wherein at least one of the compositions is free of a propellant. 21. The dual dispenser of claim 1, wherein at least one of the compositions further comprises a coloring agent. 22. The dual dispenser of claim 1, wherein the second composition further comprises a suspending agent. 23. The dual dispenser of claim 1, wherein the second composition further comprises from 5% to 90%, of a cross-linked polyacrylate polymer. 24. The dual dispenser of claim 1, wherein the second composition is substantially free of a material selected from the group consisting of a propellant, ethanol, a detersive surfactant, and combinations thereof; preferably free of a material selected from the group consisting of a propellant, ethanol, a detersive surfactant, and combinations thereof. 25. The dual dispenser of claim 1, wherein the first composition is substantially free of a material selected from the group consisting of a propellant, microcapsules, a detersive surfactant, and combinations thereof; preferably free of a material selected from the group consisting of propellant, microcapsules, a detersive surfactant, and combinations thereof. 26. The dual dispenser of claim 1, wherein the carrier is water and the second composition comprises from about 0.1% to about 95% by weight of the second composition of the water. 27. A method of providing a longer lasting fragrance, the method comprising spraying the first and second composition using the dual dispenser of claim 1.
