Which replacement head fits my Philips shaver?

Philips has sold a Series 5000 shaver for ten years and it has been three different shavers in that time, with three different heads, and the box of the one you own went in the recycling in 2021. The heads come in a blister pack with a code on the back, SH50 or SH71 or SH90, and the code is the whole question, because a head from the wrong design clicks on, or seems to, and shaves like a spoon.

Find the model code on the shaver, S5588 or S7786 or SP9883, printed small on the back or the bottom, pick it, and the sheet gives you the head code Philips says it takes and the pack. If the code on yours is not in the table yet, Philips’s own finder is linked at the foot; the sheet grows as people look models up.

2The model number, not the series

Philips says it itself, on its own support page: check the exact model number, not just the series, because shavers within one series can take different heads. The number is on the back of the handle, S5588/30, S9986/55, SP9883/36, and the part before the slash is the shaver. The part after the slash on a head’s box is a pack code, HS85/18 and HS85/53 being the same head in different packaging, and Philips says it does not matter. So: read the handle, find it in the table, buy the code before the slash.

3Series 5000: three answers to one name

The Series 5000 is the worst of them. The rounded design of 2015 to 2020, the S51xx to S54xx, takes SH50. The angular design from 2020 on, S55xx and S58xx, takes SH71, and Philips’s SH71 page says in as many words that it does not fit the rounded 5000. The odd ones out are the S5465, S5466 and S5467 and the 5000X, which take the cheaper SH30. The Series 6000 of 2019 is the rounded design and takes SH50. If you are holding a Series 5000 and cannot find the number, the shape of the head decides it: round shoulders SH50, flat angular shoulders SH71.

4Series 7000, 8000, 9000 and the Prestige

The 2015 Series 7000 was sold with SH70, which Philips has replaced with SH71, and the 2020 Series 7000 takes SH71 from new. The 2014 to 2018 Series 9000 was sold with SH90, which Philips has replaced with SH91, and SH91 fits every Series 8000, every Series 9000 and every 9000 Prestige. The Prestige has its own wrinkle: SH98 fits only the rounded Prestige models (SP981x, SP982x, SP986x) and not the angular ones (SP983x, SP984x, SP987x, SP988x), which take SH91 only. A rounded Prestige takes either. When in doubt on anything from an 8000 up, SH91.

5Series 1000, 2000 and 3000: SH30

Both designs of the Series 3000, the 2016 one and the 2019 one, and the 3000X, the Series 1000 and the Series 2000 all take SH30/50. The one catch is a different pack: SH30/20, the two-pack, is for the old Click & Style and the Star Wars SW170, not for a three-head shaver.

6SensoTouch, Arcitec and the HQ shavers

SensoTouch 2D (RQ11xx) takes RQ11; SensoTouch 3D (RQ12xx) and the Arcitec (RQ10xx) take RQ12. Philips’s page says RQ12 has been replaced by SH70, that if SH70 is also gone there is no replacement, and that SH71 does not fit a SensoTouch or an Arcitec. Those heads are getting scarce; buy them while the table still finds one. Of the older rotaries, HQ8 has been replaced by SH50, HQ9 is for the Speed-XL, SmartTouch-XL, PowerTouch Pro and AquaTouch AT9xx, HQ56 for the HQ6000s, HQ6 and HQ5 for older ones still.

7How often, and the OneBlade

Philips says to change rotary heads every 24 months, and its line is that in two years the heads have cut nine million hairs. Newer shavers light a symbol when the time comes. The OneBlade is a different thing: a blade, not heads, and Philips says it lasts about four months, with a patch on the blade that turns green when it is done. The original blade (QP210, QP220) fits every OneBlade handle; the 360 blade (QP420) likewise; the OneBlade Pro of 2018 to 2021 lists QP310; the Intimate lists its own QP219. The table gives the blade Philips lists against each handle.
